Chevy/GMC square body truck fiber optic ashtray light.  This one fits the 5/8" light socket, some were 1/2", please verify what you have.  The clip on the ashtray end is present as shown in the photos, they are often broken or missing.

I ship all parts in one day, and often the same day if the order is received soon enough.  If you see a longer ship time listed, I am out on a Jeeping trip and will mail your item(s) as soon as I get home.

I buy and sell on eBay to support my Jeep habit!  Check my feedback and bid with confidence.  Please check out my other auctions!
