I did not realize that the light bar on the Rallye gauges uses four 1893 bulbs. SuperBrightLEDs does not offer a suitable "pop in replacement" bulb. So, I bought a standard dash light bar off Ebay for dirt cheap. ($10) They are plentiful. (Rallye light bars are insanely priced, if you can even find them) I bought 4 "festoon" bases/sockets from SBLeds for $1.19 each, and 4 "festoon" uv LED bulbs for $4.99 each. I will cut off/out the original bulb backings off the light bar, cut additional holes where appropriate, and epoxy the festoon bases on, and wire it up. The SBLed site says that their bulbs work with the original dimmer on the car. The festoon bulbs have a 30 degree viewing angle, and the bulbs can be rotated in the socket for best light aiming. I'm thinking this will be EASY and cheap! lol. I just jinxed it. I will get a cheap camera and take pics as I do the mod.
