[QUOTE="machoheadgames, post: 432660, member: 18789"] Two problems. One is that your side marker bulbs are probably not non-polar. The side markers end up seeing current in both directions at times so they have to be a non polar bulb to work properly in stock form. Being nonpolar means it doesn’t care which wire is ground or power. The bigger problem is you installing LEDs in the front sockets. The side markers depend on the front glass bulbs for ground. They ground through the filaments. LEDs do not allow this to occur. The solution is the diode/resistor mod which is where you rewire the side markers to no longer depend on the front bulbs for ground. The current wires going to the side marker are parking lamp, and turn signal. Each of those needs to be cut and have a diode wires onto them, and then a small inline resistor on the parking lamp wire to waste current. Then those two wires get spliced together after the diodes and resistors. The diodes will keep either circuit from backfeeding the other. Those spliced wires go to one side of the side marker socket. Then you splice on a wire to the other wire of the socket and run that straight to a ground point. Screw on the fender or whatever you want to use. The trick for the resistor is to buy a kit and play around with what ohm rating you like. The idea is to use something that dims the parking lamp as much as possible while still keeping it visible at night. I use VLEDS 26-LED amber bulbs which are super bright on full brightness. I believe I’m using 560 ohm resistors on mine. What you end up with is a dim running lamp, and then when you turn on the turn signal the bulb gets full unresisted power so it lights up full brightness on top of the dim parking lamp mode. It essentially operated a 2 wire bulb as a 3 wire bulb. It will blink with the front bulb 100% of the time and will never alternate anymore. Here is a good write up for it in case my writing off the top of my head is unclear. Overall not too bad at all, just some simple splicing. [URL='https://wranglertjforum.com/threads/using-leds-in-the-front-fender-side-markers-on-a-jeep-wrangler-tj.32114/']Side marker mod[/URL] Here is mine. I run VLEDS 70-LED switchbacks up front which are white when on and amber when blinking for signal. Kind of a cool modern touch. Of course you need clear or smoked housings for that. Hope this helps.
