Think I'm onto something here. I'm tired of the crappy gauge lights on these cars. I've done the foil and new bulb route but it's still marginal. Last week I found some LED light strips that use ultraviolet (black light) LED's. Not knowing how the stock or white panel gauges would reflect the UV LED's, I had an extra gauge cluster and used that for my test rig. The picture below is the panel with 12v applied and two layers of blue painters tape over the LED's just to tone them down (temporary fix for now).
Please disregard the little flash-ups on the bottom. They don't really exist in real life but my smart phone doesn't know that and amplifies them regardless. The picture is without the bottom stock lights fired up so there will likely be some extra illumination of the white lettering/numbers, if they are included in the final installation.
Please respond with your opinions of this approach. The fix basically costs $15 in materials, a 1/4" drilled hole and a little wiring. Let me know what you guys think.
