The side marker lamps don't have a ground. They're tied to the Parking lamp and Turnsignal hot wires. LED bulbs will not work in the front sidemarker T10 peanut bulb sockets.
-At night properly working side markers will go dark when the turnsignal lamp lights and light up when the turnsignal goes dark.
-During the day the side marker lamp will light up synced with the turnsignal on each side.

You can get away with decent LED bulbs in the tails but you'll want to find bulbs that are designed to use the reflector dish in the taillamp.
1156, 1157, and 168 Sylvania ZEVO bulbs are designed to work properly with the filament bulb reflectors and you can get em at O'Riley.


Okay. So what I have now is park and signal wires going to the side markers. Ground and turn wires (park wire is not wired in at the moment) going to the new front led light (got rid of the factory peanut shaped bulb). I didn't replace the factory bulbs with led, I replaced the factory socket and put in a hot/ground wired led “bar”. Will this have any negative effect on the front end lights when I hit the turn signal lever?

Here is the link to the light…
