Led Tail light bulbs do not work

[Markus Escamilla]

So I bought new tail lights and i swapped in led bulbs rather than the factory bulbs. Running lights, and reverse lights work perfectly fine but when i step on the brake or put my turn signal on the lights do not get brighter or flash for turning. To attempt and fix this i bought an led flasher relay. This did not fix the issue. Next I wired in led load equalizers and still nothing. I even pulled the led flasher relay and put the old one in and still nothing. I then put the old bulbs back in and they work as they should.

 

What should do?

How many metal contacts are at the base of the new bulbs?  Not certain but it sounds like the old bulbs (correctly) have 2 contacts:  One for the regular lighting and the other for flashing.  If the replacements have only one contact point, then they aren't flasher bulbs like the old ones.
