Well the lights on my 05 civic lx auto cluster(red ones) are pretty dim now, I was looking on AllData and online but I can't find a bulb size. Anyone have any idea what size they are?

 

Have you adjusted the dimmer? Does that not help, or is there one or more burnt-out bulbs?

Should be #74, but you might as well remove the cluster and take the bulb(s) with you when you buy replacements.

 

They are about $3 each from Honda. Just get them there

 

2005 civics have LEDs. Replace the cluster or re-solder in an LED.

FYI: The ones your talking about are also in EVERY vehicle made in the last 20 years. You can get a handful at the salvage yard for a dollar or 2.

 

03-05 models with the Nippon Seiki type cluster have a mix of LED's and bulbs. The indicators are LED, the gauge lights and the cruise control indicator are bulbs.

03-05 models with the Visteon type cluster are strictly LED.
