I removed third brake light cause it stopped working. Can anyone share how to test it? Thanks

 

The only way I would thing of is running two test wires from the two battery terminals to the two pins on the back of the light. Be very careful to not touch the two wires together. There in an LED tail light repair company on the internet if yours is bad. Once in a blue moon one comes up on Ebay but if you go that route be sure it is guaranteed to work.

 

Sorry, I was thinking you had a roadster. The check would be the same however the ones for the coupes are pretty easy to find on Ebay.

 

I will be testing mine when it arrives
I found one of the hard to find LED brake lights for my Roadster
It was posted on a Crossfire group page on Facebook being provided by a member who has a salvage car
He provided me this pic....Hope it works when it arrives

 

And just as I was about to test mine I discovered this on the website for the company that repairs them >>http://www.ledfix.com/

 

I am so glad that I had not tested my 04 Crossfire Coupe when I saw that it should not be done with battery!!! Special Thanks!!!
