I had installed rear LED bulbs in place of the dual filament 3157 bulbs on my
91 Bronco. Has anyone tried the LEDs yet? The ones I got are nice and bright. I noticed my rear antilock light on the dash popped on about 5 mins after I drove down the street. Could it have anything to do with the bulbs? It never came on before. I only heard, sometimes you have to use a load resistor inline with each bulb. But I thought that was only if they dont blink or dont light at all even. My rears work like the dual filament bulbs as advertised. The front will turn on but not blink, so I could see load resistors in the front at least. Says to install the resistor on the Hot/Turn wire. The other end goes to the ground wire at the bulb assembly. These dual filiaments have 3 wires though. I didnt know what 2 wires to use then.- posted
