So I figured that I would be smart and upgrade all my 3157 lights to LEDs, of course had to upgrade the multi-purpose flasher and did to an EP27 and all that works great BUT my tail lights don't come on!

Backups work fine, flashers work fine stoplight works fine BUT no tail lights.

Any suggestions? What did I miss?

Thanks in advance!

 

Can you confirm the lights you used for the taillights have built in resistors?

 

Good question, I don't know!

 

they all have resistors.
Your turn signal switch is probably bad.

 

That's what i thought, then i got some cheap crap ones from China over eBay.

 

Could be but my turn signals aren't the problem!
They work fine, it is my tail lights. I have put all the standard lights back and everything is back to normal.

I will check the resistor issue, I had forgot about that.
