LED Tail Lights

I purchased the Sylvania Zevo LED to replace my 1157 on my 67 Mustang, but they will not blink, however they stay stuck on Bright like they wanted to Blink. Do i need to add a resistor before the light socket? Or add something else?

I'm not completely familiar how a '67 works, but you may need to install an LED compatible flasher. I did with my '69. The resistor idea may work as well.

I did resistors on a '40 as I did the taillights only. After words I found they make special flashers for the LED bulbs, and I think even ones for mixed LED and regular bulbs. The LED's don't draw enough voltage to trip the flasher unit..

Buckle up- I wanna try something!!

PM GTONavy on this forum and see if he can give you some insight. I purchased his sequential tail lights and he had me install a different flasher for his tail lights.

Conventional flashers work on circuit resistance causing a bi-metal strip to heat up and bend, breaking the circuit, then cooling and re-establishing contact. LED's have much less resistance and won't heat the strip enough to bend.

You can either replace the flasher with a solid state unit that doesn't rely on load, or add resistors to make up for the lost load.

The low current draw of the LED's require a flasher compatible with the lower current.

You will need an LED flasher (turn and hazards) like this one.

Accessories

It must have the extra ground wire.
