Expert Answers about Chevrolet Emergency Vehicle Lights


  • Red Brake Lights on Trailer Flashing Instead of Amber Lights for Hazards Using Tow Ready Converter
  • The internal circuits on the Tow Ready Vehicle to Vehicle Tail Light Converter # 118158 will send the circuit from the emergency flashers on your Explorer through the stop light wire. This is actually normal operation for the converter and there's not really anything you can do to configure it so that it powers the amber lights instead. Most US vehicles use the brake light circuit to activate the hazards, so when the circuits are separated by the converter only the brake lights will be...

  • Brake Controller Light Flashes When I Turn on My Emergency Flashers on a 1991 Ford F-350
  • This is a common problem on older vehicles. With the flashers on, the brake controller light will blink. If you have a trailer connected it will also pulse the trailer brakes, which you do not want to do. If you will need to use your flashers while towing an electric brake equipped trailer, you will need a Pulse Preventer like part # 5501.

  • Will the Tekonsha T-One # 118461 Carry the Emergency Flasher Signal on a 2009 Subaru Outback Wagon
  • Yes, the Tekonsha T-One # 118461 uses a standard 4-Way Flat connector which carries running lights, left brake/turn signal, right brake/turn signal, and the ground. The flasher signals would draw off both the left brake/turn signal and the right brake/turn signal. This is a confirmed fit for your 2009 Subaru Outback Wagon and I have attached an installation video for you to reference. If you don't already have lights I recommend the Hopkins Magnetic Tow Lights # C6304. These don't connect...

  • Will Enclosed Trailer Interior Lights Drain Breakaway Battery Without Power from Tow Vehicle
  • Unless there is a battery isolator like the Buyers Products # 3376391050 on your trailer and it is set to off then your interior lights should pull power from your breakaway battery. The only other thing that may be preventing this is if your breakaway battery is dead. Since tow vehicles only provide a slow trickle charge on the 12V power wire if your battery is dead this would make sense. I recommend taking your breakaway battery to get it tested. If it needs to be replaced I recommend...

  • Is the Center Pin on a 7-Way Trailer Connector for Reverse Lights
  • On most vehicles the center pin on a 7-Way trailer connector is indeed for reverse lights. Sometimes it can be an auxiliary 12-volt source (in addition to the 12 volt that is already there) but this is not all that common. You can test it by using a circuit tester such as # PTW2993. Chock the wheels, have someone sit in the vehicle with the emergency brake on, their foot on the brake, and then put the vehicle in reverse while you test the center pin. If it lights up the tester when the...

  • Is it Legal to Use Prostrobe Rocky 8 Pro - White Windshield Light Strobe Light on a Vehicle
  • Prostrobe Rocky 8 Pro - White Windshield Light # PRS70747 should only be used in emergency situations. For example if the vehicle is stalled on the side of the road and you need to be visible to other drivers. It isn't something you would want to use all the time when driving around because it is not DOT approved for that purpose.

  • Does Redarc Tow-Pro Elite Need Ford Module
  • You can install and use the Redarc Tow-Pro Elite Brake Controller # RED44FR without the Ford module as the wires are already run under the dash. But to activate the trailer brakes in emergency braking you would need to wire it to the brake light as you mentioned because the stop light switch wire from the dash does not activate those lights.

  • How to Hardwire Hopkins Smart Hitch Backup Camera HM50002
  • Hopkins Smart Hitch Backup Camera # HM50002 is made with a plug-in 7-way connector to provide the reverse light signal to trigger it, but it can still be hardwired. The red wire on the Hopkins needs to connect to the vehicle reverse light circuit; the black wire connects to the reverse light ground. You'll need 2 quick-splice connectors # SWC502905-1. You can find the reverse light wire by removing a tail light and tracing the wires to that bulb or you can use a circuit tester like # PTW2992...

  • Finding the Reverse Light Wire on a 2006 Chrysler Town and Country to Install Backup Camera
  • To find the correct reverse light wire on your 2006 Chrysler Town and Country you will have to test the wires using a circuit tester such as # PTW2993. The problem is that vehicle manufacturers could use any color wire at any given time on the assembly line if they run out of the regular color wire they use. This is because there isn't a standard wiring color code. I would get access to the backs of the reverse lights and test the wires coming from the backs of the bulbs to ensure you...

  • Functions Of The Curt Echo Brake Controller
  • The orange button on the Curt Echo Wireless Trailer Brake Controller - 1 to 2 Axles - Proportional Item # C51180 is used for trailer sway. If you are driving down the highway and your trailer starts to sway you can push the orange button. This applies the brakes on the trailer without having to apply the brakes in the vehicle. In a sway situation if you apply the brakes in the vehicle, even though it applies the brakes on the trailer it can cause the trailer to sway more. Being able to...

  • Installation Instructions for Custom Trailer Wiring for a 2009 and 2010 Volkswagen Routan
  • In order to use the reverse lights on your trailer, you will need to add a 4-Way to 5-Way adapter like # 47515. Using a circuit tester, like # PTW2993, find the wire behind your taillight assembly that carries the reverse light signal. It will have a signal when the vehicle is in reverse. Make sure you have someone in the vehicle to help you and put the emergency brake on for added safety. After you have found the reverse light wire, you can connect it to the Adapter 4 Pole to 5 Pole Trailer...

  • How to Access Reverse Light Signal on 2014 Volkswagen Passat
  • The only ways to obtain a reverse light signal to activate a backup camera like # HM50002 are to tap into the reverse light wire at one of the tail light assemblies, or if you happen to have a 7-way trailer connector on the vehicle, tap in to the reverse light signal wire that feeds the pin on the connector. Please refer to the linked photo of a 7-way vehicle socket. The center pin carries the reverse light signal in most typical applications. It is not difficult to tap into the reverse...

  • Can Red LED Strobe Lights be Used for Everyday Commercial Truck/Trailer Use
  • According to my research the only vehicles allowed to use strobe lights, like the Custer # CPL4R-STR, are either emergency response vehicles or heavy duty equipment vehicles like snow plows/highway maintenance or farm equipment. Obviously there are other times for flashing lights like when there is an over-sized load on the highway as well. As far as everyday use goes I don't think it is legal to use strobe lights. You will want to check with your local traffic authorities (or any place...

  • How To Install Pulse Preventer On Vehicle with Factory Brake Controller Port
  • The process to install the Pulse Preventer for Electric Brake Controllers part # 5501 on a vehicle with factory brake controller port entails locating the stop light switch wire in that harness (usually red) and splicing into this between the brake controller side and vehicle side. The other wire then get tied into the brake light circuit on the vehicle. I have attached a wiring diagram for you below. Please note, the pulse preventer is designed to allow you to tow a trailer with electric...

  • Will The Curt Universal Tail Light Wiring Kit Also Activate The Brakes On The Towed Vehicle
  • No, the Curt Universal Tail Light Wiring Kit for Towed Vehicles # C63CR is just to transfer your turn and braking signals from the motorhome through your towed vehicle so that drivers behind you can see them. To activate the brakes in your towed vehicle you would need a supplemental braking system like the Brake Buddy Select 3 Portable Supplemental Braking System # HM39524. This braking system offers intense, emergency braking or steady, smooth braking in a single portable system. Easily...

  • What Does the Black Box Do for the Ford LED Lighted Emblem
  • The little box that you mentioned is a converter box meant to separate out a turn signal function from a brake light function so that the lighted emblem # RP86620 does not blink when a turn signal is activated. The light itself should have 1 ground wire and 1 power wire. If you attach the power wire to a running/head light wire on your 1986 Mustang then it will light up when the vehicle lights are on and turn off when the vehicle head lights are turned off. I also caution you about having...

  • Wire Functions To Install Curt Powered Taillight Converter C59236 On 2011 Mercedes 350 GLK
  • The best way to determine which wires carry which tail light function is to use a circuit tester, like part # 3808. You will want to have a friend help you. With the vehicle in park, emergency brake engaged and the keys in the power mode, have your friend operate the tail lights, brake lights and turn signals as you test the wires. I have linked instructions for the Curt Powered taillight Converter, part # C59236, as it should be installed on your vehicle exactly as the instructions state....

  • How to Find the Reverse Light Wire on a 2004 Lexus RX330
  • First, located the taillight wiring behind one of the taillights on the 2004 Lexus RX330. Then, use a circuit tester, like # PTW2993, to probe each of the wires until you find the one that carries a signal when the vehicle is placed in reverse. You will need to have someone sit in the vehicle cab and put it in reverse. It is a good idea to apply the emergency brake, regular brakes, and even chock the wheels to prevent the vehicle from moving while in reverse. Once you have found the...

  • Tapping into a Reverse Light Wire to Install Bully LED Tailgate Light Bar on 2012 Ford F-150
  • There are a couple of ways to wire the reverse light circuit from your 2012 Ford F-150 to the Bully light bar # BLS-1103. First, if your truck has both a 4- and 7-Way connector (or even just a 7-Way by itself) you can tap into the wire that goes to the center pin on the 7-Way. The other way is to use a circuit tester such as # PTW2993 or a meter if you have one to test the wires going to a reverse light bulb. Chock the truck wheels, have someone sit in the vehicle and apply the emergency...

  • Testing Vehicle and Trailer Wiring to Install a 5-Way Flat Trailer Connector
  • In order to determine the wiring functions, you will need to test them with a circuit tester like # PTW2993 if needed. On the harness that you referenced, # HM37908, white is ground, brown is running lights, yellow is left turn/brake lights, green is right turn/brake lights, and blue goes to the reverse light circuit. Many vehicles have separate turn signals and brake lights so on those vehicles a converter is needed. Converters can be vehicle specific so I would need to know the year,...
