LED tail lights / bulbs

Didn't flash when I replaced the stock 1157 with LED replacements. Replaced right hand side relay flasher with NAPA part # EL-12 electronic Flasher problem solved. Posting for a search reference :]

You should replace your emergency flasher relay as well.

1992 OCC now with 5.7 tbi, DEH P77DH

So what is the reason why this relay works? Also, is the 4 way flasher the same style, blade wise?

The relay is not really a relay, it is an electronic flip flop switch. It does not rely on a bi-metal strip to actuate. There may be a similar switch for the flashers. I do not know what the part number is. I believe the polarity may be different for the flasher unit.

I my case I didn't replace the stock front turn signal lights so there is enough resistance that the stock flasher works when the flashers / turn signals are on.

4 way flasher is the same yes

The reason it's needed when changing to LED's is the old one requires some resistance in the circuit to make it work. LED's don't have enough resistance.

On related note, I recently got the new sylvania zevo led in 3157 for my truck and Like it. Have any of you tried the 1157 version?

Mine were the "Y" type that throw all of the light back toward the reflector.
