Now Off road, driving and long distance lights are so small and inexpensive I don't see why you would need it.Buyer beware though. I burned up two bulbs messing around with keeping them on (I could pull the stalk back and the dims would stay on till I released the stalk. I would drive while holding the stalk back to be in "Ultrabright" mode. Think stupid kids on dirt roads in the woods and not kids bothering other traffic.
On my S10 the low beams (outboard light) would turn off when you turned on the highbeams (inboard).
The headlights were all one piece as seen here:
The relay I used in these would have all 4 on; so on this one it made sense.
The other thing I had in them was Silver Stars Ultras so they were a pure white beam they cast.
I did mount driving lights under the bumper, but after a while I found I never needed them.
