changing greddy EGT backlit color?

[sids]

anyone tried this or has done it? ther are only two allen screws at the back and when i removed them, the gauge just rattled inside the metal canister. I do want it to maatch my blue VDO boost gauge

Im sure its possible, You gotta find out what kind of light its using. Like is it an LED? im sure it is. Then you gotta find what Mili-amps its using. I forget what the Obrevation is. Then find a LED of the same color as ur VDO one but has the same Mili-amps as the Greddy stock one, and Remove and replace.

I'm still stuck on how to take the gauge apart

the two scrwws just loosen the internal bits, but the gauge is still one piece
