Combined Parking/Turn Signal Lights - 4Crawler Unless the snow is periodically cleared, it will mask the front turn signals. Also the wiring is exposed behind the bumper, directly in front of the wheel well. My other vehicle has a fender-mounted turn signal/parking light assembly that utilizes one socket holding a #1157 dual-filament bulb. This seemed like a better solution, so I set about How-To: Wire LEDs as Parking Lights and Turn Signals Nov 19, 2008The turn signal and hazard lights need to be the full brightness of the light, so no resistor is required on their power wire. I did wire a diode into this lead to prevent the power from the parking lights from feeding back through the turn signal lead.
