Guage that doesn't light up, Guage that doesn't light up Options

[CelicaSweden]

When i removed my guages last week won't it light up and i dont know why ?
Does anyone have/had the same probs that i have ?
I have meusured the Voltage and checked the circuit breakers but it still don't work : /
I have also checked the diods and they are okey.
Can someone help me ?

there's some stupid things i always do that repeatedly cause the lights to go out. usually they're worth checking out, i guess.
make sure the dimmer knob is blugged in well, no dimmer, no lights
if using leds make sure your polarity is corrent.

aside from that make sure each socket is getting 12volts, and then make sure the leds/bulbs are making good contact with them.

i hope it's one of these easy to solve mistakes.
