Instrument Panel Bulb out

Anyone know what kind of bulbs are behind the instrument panel. My blazer is a 2003, the bulb that went out was the one behind the oil pressure guage.
Does anyone know how to do this without taking the whole dash apart?
I know this is wishfull thinking, and I know the answer, just double checking.

The only bulbs used are for the turn signal indicators, high beam indicator, and cruise control indicator. All others are light-emitting diodes (LED). If an LED fails, the instrument cluster must be replaced.
