Expert Answers about Emergency Vehicle Lights

• Recommendation for Magnetic Tow Lights That Can Be Used as Back-up Should Trailer Lights Fail
• It sounds to me like you are looking for a spare set of lighting that would allow you to move your trailer even if the trailer's lighting had failed. If this is the case, if your tow vehicle is equipped with a 4 way, I would recommend going with the Roadmaster Standard Magnetic Tow Lights, # RM-2120. These magnetic lights ensure that you have emergency flashers and the signal lights required for towing without having to tap into existing wiring. Just plug the lights in and you are ready...

• What Emergency Light Bar System Will Work with a Naked Roof?
• For an emergency light that has the benefit of magnetized and suction attachments, I recommend the Custer 40-LED Light Bar w/ Controller Box - Magnet/Suction Cup Mount # STR-40-S. The benefit of having the Custer is that if your rear door does not have a magnetic surface, it can still remain secure with the suction cups. It comes with 6 different flash patterns and hardwires to your vehicle's 12-volt system. If you already own a light bar system and need to mount it on rails, I recommend...

• Where to Find Brake Output Circuit Wire for 2006 Jeep Grand Cherokee for Brake Controller Install
• When Jeep installed the factory 7-way on the third generation Grand Cherokee, they ran the brake output circuit from the 7-way under the vehicle and into the passenger cabin below the dash. The output wire is either light green or blue in color, and should be bundled up by the emergency brake area (if a pedal style was used). The wire should have a tag or sticker that says 'trailer brake.' If for some reason your vehicle just does not have that circuit you can bypass the headache of trying...

• Emergency Battery Powered Trailer Light
• I believe what you are referring to would be something like the Roadmaster Magnetic Tow Lights # RM-2120. These attach to either your 7-way or 4-way. I attached an install video to show you how easy they are to use.

• Troubleshooting Trailer 7-Way Wiring Where Only Running Light Circuit Functions
• I would get a circuit tester like the part # PTW2992 to test the pins on the vehicle side of the wiring for voltage when the various taillight signals are applied as this will tell you if the problem is on the vehicle or trailer side. If the voltage is on the pins correctly it's the trailer but if not it's the vehicle and you'd need to basically trace wires to find problem and fix as needed. You can also check the fuses under the hood as that can sometimes be the issue as well.

• Recommended Exterior Flood/Spot Light for Emergency Response Box Trailer
• The Tow-Rax Recessed LED Light # TWSPRLB2L is an extremely bright light at 4500 lumens. We also have the Opti-Brite Mini LED Work Light - Flood Beam - 3 Diodes - Black Aluminum - 2-3/4" Square - Qty 1 # TLL52FB which is rated for a raw lumen output of 600 lumens.

• Recommended Tail Light Converter For 2016 Jeep Patriot
• Yes. You will need a tail light converter like # 118158 to hardwire your system to function properly. If you want to use the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56333 it will come wired to convert from your factory quick connect behind each tail light and draws power from the battery to protect your system.

• Charger Recommendation for Charging Battery of Dump Trailer
• For a charger for your trailer's battery the best option we have is the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1240D which is designed for putting up to a 40 amp charge on a battery that is rated higher than 200 amp-hours. The fuse kit you'll need then is the # 331-FK60. I know it's not exactly inexpensive but charging a larger battery while towing requires a special charger setup. For a 7-way with junction box to make wiring up the lighting and braking of your trailer the #...

• No Driver Turn or Stop Lights on Trailer with 2015 Ram 3500 Tow Vehicle
• It sounds like the left stop/turn signal fuse is out on your 2015 Ram 3500. In order to check this you will want to pop the hood, find the power distribution center (PDC), and locate the yellow 20 amp F53 fuse which is labeled, "Trailer Tow – Left Turn/Stop Lights". If the fuse is bad then replace it but otherwise you have a wiring issue or error with the body control module (BCM) and you will need to take your truck to a repair center for service.

• Troubleshooting Trailer Lights that Don't Work When Headlights are On
• It sounds like there is too much amperage being drawn on your trailer when the headlights are on and it is too much for the trailer so everything shuts off. This could be because of a bad ground somewhere. First thing I would do is check the grounds on the trailer for any loose wiring and corrosion and fix as necessary. If the grounds are good you might need to convert your trailer lights to LED lights so as to minimize the draw on the trailer light circuits. LED lights draw a fraction...

• Brake Controller that Works with Emergency Braking of 2019 Ford Ranger
• I have a similar brake controller solution that does work with the emergency braking system of your 2019 Ford Ranger with the P2 part # 90885 and the diode kit part # 7865 but Redarc doesn't have a diode kit yet to allow the Tow Pro Elite part # RED44FR to work. This controller will work a lot better than any OEM controller for sure.

• Installing a 4-Way to 5-Way Flat Adapter on a 2011 GMC Terrain
• Even though the actual reverse lights are located in the rear hatch of your 2011 GMC Terrain there could still be a wire that carries a reverse light signal behind one of the taillights. To find it you will need a circuit tester such as # PTW2993 to test the wires behind a taillight while someone sits in the vehicle and puts in in reverse (with their foot on the brake, emergency brake on, and the wheels chocked. Safety first!). If you cannot locate a reverse light wire this way, then open...

• Powering Interior Lights of 2010 Lark Enclosed Trailer
• It sounds like the interior trailer lights are wired to the auxiliary 12-volt circuit from your 7-way that is only powered up when the tow vehicle is running. Since LEDs use a fraction of the power that incandescent lamps do, I would recommend using LED interior lamps. Since it serves such an important purpose, I cannot recommend tapping lighting circuits into the break away battery. A better idea would be to use a separate 12-volt battery installed on the trailer to provide power to the...

• Adding a 5-Way Flat Trailer Connector to a 2012 GMC Acadia
• In order to install a 5-Way flat trailer connector on your 2012 GMC Acadia you will need 2 items. First, since your model does not have the factory tow package, you will start by installing a 4-Way # 118451. With the 4-Way installed you will just need the second item which is a 4- to 5-Way adapter, # 20036. The adapter has an extra wire that will need to be spliced into a reverse light wire. You may be able to find a reverse light wire behind one of the tail lights by probing the wires...

• Recommended Emergency Strobe Light for Rear Window of 2011 Ford F-150 Crew Cab
• The Prostrobe Rocky 4 Pro - Amber Windshield Light # PRS70750 is a great option for the rear window of your 2011 Ford F-150 Crew Cab. The suction cups are very strong and more than capable of holding this light weighing about a pound. The 3 foot coiled cord will also give you the connection needed to your 12V system. The defrost grid should not be an issue with the suction cups, but ideally you'd have the suction cups between the grids if possible to ensure an even better connection.

• Can 2019 Honda Accord Manual Transmission Be Flat Towed
• I pulled up the owners manual of your 2019 Honda Accord and Honda specifies that only manual transmission models should be flat towed behind a motorhome. I'd agree that it seems any FWD vehicle SHOULD be flat-towable but since we aren't the ones who would honor the warranty of your Accord we have to recommend you stick with Honda's recommendation. For a base plate kit that fits the Sport models of the 2019 Honda Accord with a manual transmission we have the Roadmaster part # RM-521572-4....

• Adding a 4- to 5-Way Adapter on a 2015 Toyota Highlander
• What you will need is a 4-Way to 5-Way adapter, # 20036. You will have to splice into the reverse light wire to install the 5th wire (blue). You mentioned that the wires go from the rear hatch into the roof of the vehicle. If you pull or cut back the covering on those wires to reveal the actual wires you can use a circuit tester such as # PTW2993 to test them to find the reverse light wire. What you will need to do is chock the vehicle wheels, apply the emergency brake, and start the motor....
