Expert Answers about Kenworth Vehicle Lights

• LED Vehicle Lights With Incandescent Trailer Lights
• In order to safely avoid overloading your vehicle's wiring system, you would need to have a trailer wiring harness with a powered converter that supplies power to the trailer lights similar to the Curt Powered Tail Light Converter with 4 pole flat # C59236 . If your vehicle has a factory tow package that came with a wiring harness installed, you'll likely already have a powered converter installed in-line with the wiring harness. This allows you to safely run the incandescent trailer lights...

• When Should My Trailer Lights Be Working
• When the vehicle is not running and the key is in the off position, the only functions that should be working on your vehicle and trailer will be the headlights and tail lights as they are not tied into the vehicle's ignition system. If you vehicle's brake lights come on when the brake is applied, then your trailer brake lights should come on as well. It is likely the turn signals will not function while the vehicle is not running and the key is in the off position. When the vehicle is...

• Why are Diodes Needed for Lighting when Flat Towing a Vehicle
• When a vehicle is being towed it cannot operate its own lights. The diodes are a gateway with 2 inputs and one output. One input is the regular wiring on the vehicle. The other input is from the RV. Since vehicles being flat towed will not have working lights they will have to get power to function from the RV. The diodes allow for 2 inputs so that you don't have to disconnect the vehicle lights to plug in power wires from the RV. The tow vehicle lighting system only matters if the tow...

• How to Install a Tailgate Light Bar on a Trailer Using the Vehicles 4-Way
• The Putco Red Blade LED Tailgate Combination Light Bar part # P92010-60 which is the lightbar I recommend for your trailer has LED lights so the amp draw will be very minimal. The reason that this is important is because the total amp draw for each circuit on both the trailer and light bar cannot exceed that of the vehicle's trailer lighting circuits. I do not believe you will have any issues because the light bar has LED lights which draw much less power when compared to incandescent....

• Installing a 2-Wire Combined Trailer Light on a Vehicle with 3-Wire Separate Wiring
• It sounds like you're trying to use trailer tail light, part # STL201RFMB, which is a 2-wire system on a vehicle that has 3-wire separate wiring. The light is designed as a trailer light, and trailers generally use 2-wire lights but the light can work on a vehicle with separate lighting if wired correctly using a converter. You need a converter like the Roadmaster Brite-Lite, part # RM-732, to combine the turn signal and brake light circuits on your vehicle. Connect your vehicle's brake...

• Will Auxiliary Lights on Tow Vehicle Automatically Light Up When Connected to Reverse Circuit
• As long at the center pin of the 7-Way connector on your tow vehicle receives power when you put the vehicle in reverse then auxiliary backup lights will light up automatically when you put the vehicle in reverse. I do recommend installing diodes like part # RM-690 just to ensure that any issues that may arise with the auxiliary lights doesn't backfeed into your vehicle wiring.

• How to Power a Separate Clearance Trailer Light
• Having to run a separate wire to power the collision avoidance light on your trailer will depend on how and when you want that light to illuminate. If you want that light to be on only when the running lights are on, then you would not have to run a separate wire. You could simply cut the wire at the 6-way trailer connector and splice it into the running light circuit. If you do not want the light on all the time and you want the ability to turn the light on and off as you please, then...

• Are Towed Vehicle Lights Required to be Active when Being Dolly Towed
• Typically the lights on a vehicle being towed on a dolly don't have to be active, but it is always best to check with local authorities to ensure that you are abiding by the dolly towing laws. With that being said, some people still prefer to install magnetic towing lights on their towed vehicle just to make sure that everyone around them knows what is going on. The Heavy Duty Magnetic Tow Lights # TL21RK are a very popular kit that we carry and they come with a small pigtail that you...

• Will the Wiring Harness # 118551 Protect the Vehicle Tail Lights on a 2011 Ford Van
• The converter box on the Tow Ready T-One Wiring Harness, # 118551, is rated for a maximum of 4.2 amps for the stop and turn lights and a maximum of 7.5 amps for tail lights. Assuming the two tail lights and four marker lights are the only lights that will be powered by this wiring harness, then you should not have an issue. If you want to be absolutely certain that your trailer lights will not overload the harness, you can use a multimeter to test the amperage draw on each of your trailer...

• Why Does Curt Harness C55532 Need a 12V Power Wire Run to the Battery
• This is a common occurrence on many vehicles. Vehicle tail lights have changed over the years and they use less current than they used to. Trailer lights have not progressed as quickly. What could happen with an older traditional harness that does not have the added power source is that the trailer, with the older, less efficient lights and depending on the number of lights, could over draw the tail light circuits on the vehicle causing fuses to blow. Additionally if the trailer were to...

• Is a Stop Light Relay Needed when Using the Roadmaster Even Brake on a 2009 Jeep Wrangler
• The stop light relay, # RM-88400, is included with the Even Brake, # RM-9400. You will need to use the stop light switch kit, # RM-751452 according to Roadmaster. This kit will alert you when the vehicle brake pedal is being pressed. A 12 volt power supply, # RM-9332, is also recommended. To determine if a brake light relay is needed to properly wire your towed vehicle, answer the following questions. Are you using a supplemental braking system that depresses the brake pedal in your towed...

• How Does Trailer Wiring Install on a 2008 Saab 9-3
• I attached a set of installation instructions for the wiring kit you have part # C59496 to the right. But basically, some vehicles (like yours I believe) combine the stop and taillight functions onto one circuit. These vehicles will require that you attach the trailer light power module red stop wire to that same circuit on the vehicle and then ground the brown tail light circuit. Some vehicles combine stop and tail light functions onto 1 circuit and then also have an additional tail...

• Do Thule Transporter Enclosed Cargo Carrier Lights Have to Be On if Vehicle Tail Lights are Visible
• If the Thule transporter, # TH665C, does not block the vehicle tail lights, then you do not have to connect the lights on the carrier (check local and state laws to be certain). If the 2012 GMC Terrain came with a 4-Way trailer connector, it should be plenty strong enough to power the simple stop, tail, and turn lights on the carrier. If you are experiencing a problem, it could indicate that something is wrong with the wiring on the vehicle or carrier. Since it is a new vehicle, it...

• Are Lights and Supplemental Braking System Required on Vehicle Being Towed on Roadmaster Tow Dolly
• The Roadmaster Tow Dolly with Electric Brakes # RM-2050-1 that you referenced provides brakes and lights while towing a vehicle on the dolly. The tow vehicle will need a brake controller and need to be wired for electric brakes to control the brakes on the dolly. To use the electric brake function, the 4-Way flat connector on the dolly will need to be changed out for a 6-Way connector, # PK11604, or a 7-Way connector, # PK12706, with the new connector wired by function to match your tow...

• Wiring Ground and Running Lights When Using Vehicle to Vehicle Tail Light Converter 118158
• When wiring in Tow Ready Vehicle to Vehicle Tail Light Converter # 118158 the tow vehicle's combined stop/turn signals and ground do connect at the input side. The ground connection will be split at the input side to also allow it to be run over to the output side as well. The running light wire on the tow vehicle (usually a brown wire) will also bypass the converter since it does not require any processing. The linked image illustrates.
