Default Check Engine Light/Gauge Cluster HELP!

In short, I failed emissions (upstream o2) and didn't have a CEL. I put the key to on and noticed all of my cluster lights work however my CEL was not lit up, meaning it is either not receiving current or the bulb is burnt out or more likely removed. I examined the board and the circuit is not scratched or broken and all contacts look normal. Everything else on the cluster works.

I'm wondering what type of bulb I would use to replace it; I have enough soldering experience to do the job but I can't find any information on what type of bulb to use or are they fairly universal? Thanks I hope somebody has looked at this before.

I think power is supplied to the light when the igntion is ON and the ground for the lamp is completed inside the ECU when the lamp is supposed to be turned on. You should have voltage on the hot lead to the lamp when you turn on the ignition. If the lamp is in place and you want to verify it is ok then just touch the ground side of the lamp to a grounded jumper wire. If the lamp tunrs on then either the return wire to the ECU has a open connection or the ECU has a fault. You should be able to ground the wire at the connection to the ECU to verify the wiring.

Thanks! I will try that today and probably go buy a yellow led at radio shack and bridge the pins from the back of the board to see if it lights up as well but that should help me diagnose if it is a problem besides the bulb because led's dont normally burn out

Thanks everyone for the help, it turned out to be actually really simple. Tricky B4$%$#$ I bought the car from put electrical tape on the back of the gauge plate and ta-da no cel.
Don't be dumb like me and make sure the cel is lit when the key is turned to on before you buy any car

You're not the first one this has happened to. It is very easy to overlook that check but it is really very important to do. Thanks for the update.
