LED 1157 bulbs problem
Hi problem with 1157 LED bulbs .
I install all 4 light bulbs the tail lights and front turn signal lights
the problem is all lights work with the signal lights. but when I turn the head lights the front signal lights don't work. Also the turn signal lights on my dash board both light come on
one more thing if I install the regular 1157 on the front .
the LED lights on the back work fine and the from work fine .
looks like the front don't like the LED bulbs.
I have 87 ranger cab and half or extended cab.
v6 2.9
any help will be appreciated

I had a similar problem with my 97 F 350. I also had automatic trans issues because the brake lights were always partially on. I did some online research and found out that I needed a externally grounded, electronic flasher. I found this flasher, EF32RLNP, online for around 14 dollars with free shipping for prime members. The flasher stopped all of the problems I had, just make sure you get a good body ground for the external wire. Hope this helps you with your problems.

As previous posters have noted, it's a common problem. The LED bulbs just don't draw enough current to allow the older relays to function properly because the relays weren't designed for use with LEDs.
I seem to remember that some people have installed a resistor in-line with the light to make them work. Sorry I don't have any more detail for you. It was 20 years ago I read that. Maybe it will help you find a solution.
