So, I replaced the 3157 standard bulbs with 3157 L.E.D.s in all four corners. I have brake lights, parking lights & hazard flashers. But, I lost my turn signals and the anti-lock idiot light is coming on as I'm driving. I checked ALL fuses and they're all good.

Any help would be appreciated.

Not sure if the anti lock is related, but most flashers are made to work with incandescent lights which have a much higher current draw than LED's. The flasher works by the current flow heating a bi-metallic switch that opens when a certain temperature is reached (I^2R function) and then re-closes rapidly as it cools. If you don't draw enough current, the flasher unit won't work. You probably have sufficient current draw for the hazards since it includes all 4 corners of the vehicle, but with only 2 corners it's probably not enough for the turn signals. You may need a different flasher unit, or a different brand of LED bulb that has a built in resistor to make the turn signals work.

Thanks for the come back. While I was driving today I noticed that I either lost a gear or the torque converter lockup stopped working also. I changed back to the standard bulbs, went for a ride and everything works fine again. I picked up load resistors at Walmart and I'll try those. I guess they're suppose to mimic standard bulbs so I can use L.E.D.s.

Seems strange that it would cause the other issues, but with the computer based vehicles, weird stuff can happen...
