At last, there's a solution to a problem that almost all early Cougars suffer from. If the turn signal indicators in your dash only blink once, and then pulsate slowly without going out, you need this new electronic relay. It's a direct...

My older relay does not look like the one shown in the instruction. Do you have a video showing how to install this relay?

Dash indicators now work !!

My turn indicators would dimly flicker and I would constantly check my lights to be sure they were working. It took 10 minutes to change the relay and the dash indicators now work as they should. The clicking sound from the relay is there and I didn't have to adjust the unit even though I'm using LED bulbs. I highly recommend this.

I didnt think I would need this!

I had a hard time accepting the cost of this relay simply for the turn signal "click" and bulb illumination but I must say its worth it! You take for granted how nice it is to be able to have a functioning turn signal light and audible click to remind you your turn signal is on. This relay is a must have if you go with the plasma LED taillight bulbs which again are another huge upgrade that is worth every penny. With LEDs and the stock K5 relay your turn signal indicator isnt audible and solidly lit when activated but does not flash. This relay solves both those issues and a must have with LED bulbs. Made in the USA!

K-5 solid state turn signal relay

K-5 solid state turn signal relay work great in my 1968 cougar. Turn signal dash indicators flash completely on and off with a nice click sound.
