Reply to "Speedometer/Tachometer Illumination"

Mark,

I began my conversion to LED bulbs in my gauges by adding two extra bulb holders to my tach and speedo, as per John Taphorn's instructions. The only difference being, I added OEM style wedge base bulb holders. The bulbs I used were from SuperbrightLEDs.com and the part number is: WLED-GHP. These have a 120 degree beam pattern. For whatever reason, they worked very well in my speedo but not as well in the tach, which wasn't nearly as well illuminated by the LEDs. So, in an effort to increase the brightness of the tach, I added two more bulb holders but it still wasn't as bright as the speedo. Naturally, I then added two more bulb holders! I now have seven LED bulbs in my tach and three in my speedo. The results were amazing but it was tough getting there!

Since then, I've found a brighter, 360 degree beam pattern, LED bulb that fits the OEM bulb holder. It's from superlumination.com and the part number is: T10 Wedge - SMT Tower - Green - 194 Lens. SuperbrightLEDs.com has an almost identical bulb (part #: WLED-GHP5) but it needs to be filed down a bit to fit in the OEM bulb holders. I think if I had used these bulbs in the tach, it would have been equal in illumination to the speedo (with the WLED-GHP bulbs), without adding four more bulb holders and LEDs.

Hey, you asked !
