does anyone know with these tails
is the leds the only thing that lights up on them?
hard to tell from the pic, but if they are the same as the others on the market, the leds are two wire... 12v+ and ground. Meaning they will work for park or brake but not both.
There should be a hole for a standard 3157 socket to go in on the outers to act as park/brake.
I have them and yes the leds are the only things other than your stocklights. I have them hooked up as parking lights but you can wire them any way you want. Was thinking of switching to brake lights so they are of and only come on with the brake, only because the led brake light bulbs are hard to see in the day light.
Ps don't buy the ones from spider, they burn out fast. The more expensive ones are worth it.
