I just put in a 91 Civic cluster in my 91 DX. Everything comes on as in blinkers, froster buttons but my gauges won't light up. This is probably a simple answer but can someone tell me what size bulbs fit in the back of the cluster? Thanks

you can use the bulbs from your other cluster to see if the bulbs are infact out.

finding replacment bulbs is rough....

 

I tried that. On my DX cluster the bulbs are huge as also the plugs when you unscrew them. On the Si the plugs and bulbs are alot smaller than the DX so I'm trying to get the bulb numbers to see if I can replace them and get it to work right.

 

I had a problem just like yours. Just go to your local junkyard and pull outs lots of cluster bulbs from 88-94 honda, stick it in your pocket and bounce
