Can I use this as a dome light in a trailer; can I pick up power from the running lights with the (+) Red wire and frame ground the (-) Black wire?

Yes that will work, but remember the running lights have to be on for the new dome light to work. Might be wise to put a small battery in the trailer. Only you know how you plan to use the set up.
525912
Yes you can ! Power drain is very low . You will have to have the trailer plug connected and the lights on .
525913
The short answer is YES. Just be sure that:1. You must provide 12 volts to the lamp else it won't won't light up.2. LEDs are polar sensitive. Red to Red, Black (or ground) to Black3. You should have a black wire (sometimes white) coming through the trailer connector to trailer frame. Do not depend on a ground connection through the trailer ball4. Running lights have to be on to work.

Yes except that you will have to have your running lights on to have power to this dome light.

I don't see why not, this is a dome light also and uses less power than the traditional bulb light.

Yes, you can use it as a dome light in a trailer. Yes you can pick up power from the running lights, but the dome light will only work when the running lights are on.Most trailer frames are grounded back to the power source for the running lights, so that should work.

As long as the running lights are powered up, this light should piggyback just fine. It's LED, so uses very little power, yet lights up very brightly.

Hello Sherry . Yes you can , just hook up all the ground wires together and then all the positives together , then do your wiring as usual . LED lights draw next to nothing for power , and these switches are awesome !! Good luck and your welcome. Derek

When you attach the light to whatever you are attaching it to that acts as your ground. So you just need a positive run to the light. You can ground the adapter to the light as well I would think

This one should work. Then you need to know if your trailer is a 4 wire or 5 wire. 4 wire is the rear lights on the trailer are brake/run/turn. 5 wire is there are separate lights for turn, and then brake/run is on another light. Usually. 5 wire trailer has separate amber lights in the rear for turn signals.Depending on your trailer as mentioned, if it is a 5 wire, you just need this and you are good to go! If you have a 4 wire, then you will need the 5 to 4 wire converter.

To be perfectly honest with you, if you aren't sure about wiring, maybe this isn't the right product for you. It will mean using trim tools and splicing to a found 12v wire. If you want to press forward, the red goes to a switched +12vdc source, and the black goes to a chassis ground point. Good luck.

There are wires.I cannot find my notes but somewhere in the comments on these someone tells exactly which is turn,run and brake.Simple to wire and very good lights with excellent visibility..White wire goes to ground ( any metal surface will work). This goes for both lights. ****White wire from trailer connection also goes to any available ground. Black wire is for your running lights. ****Black wire from both lights goes to the brown wire from the trailer connection. Green wire is for your turn signal and brake lights. Connect correctly the brake lights will also work. ****One green wire from the lights goes to the yellow wire from the trailer connection. (The right turn signal) ****The other green wire from the light goes to the green wire from the trailer connection.(The left turn si

You will need to buy a voltage converter. If you splice the wire and hook it up directly you WILL damage the lights.

No, the voltage range is rated as 10V to 30V and it may run as low as 9V but if it produces any light at all at 6V it will be very dim.They are not case grounded, rather a separate wire. However all you would have to do is terminate the ground wire with a ring connector and screw that to a ground point on the chassis of the device providing power, assuming that device is chassis grounded.

Yes this will work well as dome light.LED light works best if you can have the space lighting in the corners but a car is such a small space that 1 LED in the middle will be just fine

The LED Light should have three wires, white=common/ground/frame, the black, & red or the tail light & brake/turn signal. the black & red could be reversed.I mounted the light to the frame & connected the white/ground wire under the screw. Then I only had two wires to connect to the trailer wiring.Trailer wiring varies, some have green & yellow for turn/brake lights & brown or black for tail/running lights, white is common/ground. Hope this helps.

if you have the backup lights for the trailer. you can use the adapter that comes with it. other wise you need to hook it up to your back up lights.you need to make sure that your wire is going to be long enough .

I am not sure what you mean. You can use either the black or the white wire on either the + or - terminal. But what ever you use for the plus if at some time if you wire them back wards you will short out. Electric is color blind. One way to make sure you do not short out is to say this color that is the + and make sure what ever you use for the hot you continue to use that color. If not at one time you may wire your ground to a hot and burn up your system. The red is the hot but you can use the black as your hot as long as you wire it to the + on your battery and the Roadpro. I have 2 red wires coming off my solar panel to my Roadpro. On the - I have black tape at both ends of my neg wire.

Find a 12v source I hooked it up to my night time head lights so they would come on automaticity. black(ground) wire to black wire that goes to your headlights and red (positive) goes to positive wire running to your head lights usually red but it can be any color. Just slice the wire open and use electrical tap to protect it. Good luck!

Per the sticker on the side: red wires hook up the supply +12V and load (lamp/strip) +12V. It doesn't matter which you connect where, as they are bussed together at the switch. Black wire connects to supply GND, and green to the load's GND wire. This device operates as a low-side switch, so when switched off, the device will actually have a potential of +12V.

Yes. Use in line fuse 5amp or so and Just switch the red and hook black to ground. Best place for ground is back to negative terminal or other source dont use frame. I buy black low volt landscape cable from home depot works great.

We used the led lights to replace the lights in a trailer. They replaced the lights in the trailer and worked very well. Can't tell you if the will work I. A dodge truck. They do draw a lot less amperage than the original lights.

I dont see why you cant.just hook up the positive and negative wire and you should be good to go.the led lights draw hardly any power.they are great lights and good people to deal with. Good luck
