Looking for info on led light bars for taillights

[vikingbry]

I have a 72 gm shortbox stepside and have had it in the shop getting it prepped for paint. Its just ready to go for the final paint now. I've been looking for a led light bar for my roll pan. I have a custom fiber glass box on the truck and there are was no mountings for lights put into the box. I don't really wanna cut out holes in the rollpan for lights, like the corvette style rollpans you can get for these year of trucks. I would prefer a led light bar, but can't seem to find the one I need. I need to find an led light bar that will work for tail lights/brake light/signal light. if you know any websites that carry these please post a message and let me know. Also I have found a website of a guy who made his own, unfortunatelly there was no email address to get a hold of him. If any of you have done such a project on your own please post a message also as I would love to find a way of making a custom led light bar if possible. Many thanks in advance
