Definitely! I did 2 turn signals, 2 side markers and 2 tail lights with 1 can and still have some left.

Should only need one, you would just want to wire it like a light switch with power coming to sensor then to lights.

You need two motors and two more of the stop clamps for the motor. Thats if you want the lights separate on the same rail.

Its just one light but it is very bright. I use one as an aux reverse light.

well, I was able to do both of my headlights and there is some left over but I did one of them twice. If they are not extremely oxidized you could do two cars, especially if you use an electric drill (not a cordless one).

Yes you can use this unit. Your original Guide Bars are a single brightness level. The White wire goes to ground. Think of the other two wires as Lo and High brightness. Pick the brightness you want and connect it up to your 'one wire', just don't use the remaining wire. Tail or Running Lights = DimmerStop or Turn = BrighterOld style Dual Incandescent bulbs have two filaments to achieve the dual brightness levels.LED units are able to very there brightness levels and/or turn On more individual LED's to increase brightness for Stop or Turn.

It's the tail light and the brake light bulb in one. It has two filaments in it. So it's both.

You shouldn't need one. This is as simple as unplugging the lights from the old tail lights, removing the bulbs and hooking in the new light. Just be sure to match up the hot wires properly when installing the new lights. It is relatively straight forward. You can also go to the Spyder website for installation videos

Yes, these bulbs have two brightness levels. They have two contacts on the bottom. The tail light is the first brightness; the brake, or stop, light is a brighter second brightness.

One kit will power both lights, driver and passenger. One kit for headlights and one for fogs. Use the existing fog light connector with shortest run from battery as your switch power. Make sure your fogs are 9006 as well, otherwise purchase the kit for your bulb type because the connector will click right onto your existing harness connector. Save old bulbs for when you sell truck.

Two would do both and you should have some left over. One is not enough for both vehicles.

you only need to get one...it comes with wiring and everything for the pair of lights....thats the single housing headlights that uses the h4 hi/low bulbs

No, one unit per brake light circuit, typically the third brake light, but if you wanted to connect it to you entire brake light set up, you would have to do so before the circuit enters the steering column which allows use of right and left turn signals. Hope this helps.

No, the factory headlights use one dual filament bulb ( hi & lo beam in one bulb) and these headlights are wired for two separate bulbs. And by the way I think these headlights are absolute junk the are impossible to aim correctly.

You can only tow one vehicle at a tme why would you need both connected at once
