Nope. There are no accessible bulbs. it appeared to be LED's in the dash, already had a quick squizz at mine. This is why I was also looking at other dashes... Wait... i f they r leds. The brightness cant be adjusted becuz of the threshold voltage of the resistor? Any pics of the internals? :P where they soldiered in? Was it hard to pull out if the dash and crack open? Im sacred to do mine afraid somethig might happen lol I forgot to take pics... I could take my dash apart... again for pics sake... but yeah, as far as I figured, they're soldered in, every single light on the dash, but the dash LED's themselves have the ability to be dimmed, as CME-LFT mentioned. by turning your headlights on (at least parkers) and then pushing your trip meter from the Odo (being how many Km your car has) to Trip A, then Trip B, Then once again... You should have these bars appear, if you press and hold your trip meter button in, it should start changing the luminosity of your instrument cluster...
