I just finished installing LED taillights in my 69 Camaro that I purchased from Summit Racing. Everything works except the signal lights. I replaced the flasher with an electronic one. What could be wrong? Thanks in advance for your help.

 

There are 2 flashers under the dash; one for the hazards and one for the turn signals... Did you replace both of them?

 

Flasher on fuse panel is for emergency flashers.
Does the selected side come on, but no flash?
Ensure electronic flasher is grounded good.
Ensure it has power from fuse panel.
Might try a heavy duty P/N 552 flasher.

 

The selected side comes on but no flash. Where is the second flasher located? I changed the one on the fuse panel on the firewall behind the emergency brake peddle. Four way flashers work fine.

 

The flasher needs a certain amount of electrical load in order to blink. The LEDs are probably pulling much less current than the old bulbs which can cause the flasher not to work.

 

OE turn flasher is above the gas pedal either hanging from the harness or in its clip.
If signal lights come on and no flash, try a heavy duty flasher, p/n 552, as it flashes on its own and does not need a load the work.
