Ok so I had a r everse bulb burn out so I picked up a set of the sylvanis led number 1157 I believe. I already have the sylvania led bulbs in my tail lights and they have worked well. I have a hyper flash relay installed but only one of the reverse led bulbs will light. With one led and one regular bulb it works fine or with two regular bulbs it works but put both led’s in and only one will light. Any thoughts?
I figured it out one of the bulb housings was wired reverse polarity from the other. Wired them in parallel to each other and both led bulbs light when supposed to.
IF you are having fast blinking turn signals this is commmon with LED bulbs
However there is an easy fix
You need to change your signal "flasher" from the stock mechanical flasher to an electronic flasher-----LED's use such low amperage that the mechanical flasher will not work right However the electronic one is deigned to work with very low amp draw
