68 Barracuda dash panel help

There are lots of manufacturers of LED lamps so buyer beware. I have a box with many that claimed to put out X lumens but they either failed or didn't work at all. I have been using Superbriteleds.com for a few years for personal and business projects and have had excellent luck with them.
Keep your warning lights all clear or white and get leds with the highes lumen output possible. A lumen is a measure of light intensity if you didn't already know.
I did a combo of blue for faces and white on indiscators for my fatblufish and did all white on Pams Jamaican Blue Baby. Here's a shot of mine.. Have had zero issues with my dash lights. I also have LED parking/turn and brake lights and those work awesome as well. Must have an LED flasher for the full conversion though.
SBLEDs carries them as well.
Also recommend grounding the circuit boards by running a ground wire around the ground screws that hold on the circuit boards then back to the body. Need to take out the cluster to do that though.
Good luck on your conversion and post some pics when done.
