Front LED turn signals
 

I recently put ZEVO LED's in the rear and now want to put them in the front also. Where is the easiest place to install the resistors? I would like to mount them to metal if possible. Thanx

Resistors do not need ground, they usually just solder inline. The turn signal/parking lights should not heat the resistor up enough to worry about heat dissipation.

Or get LEDs that have the resistors built in.

There is plenty of metal under the fender liner if you really want metal.

I have mine installed inline. The resistor's small and light and I cut off almost all extra wire so it nestles right in the wires.
