Okay I own a 1998 Acura TL 2.5 and I am trying to get the size of the bulbs for the dash area. Now when I say that I know that everyone is going to give me other parts but I mean like the dimmer, cruise control and the AC/Heater control unit. I want to change these bulbs also since over time they have gotten dull and I have found some nice HID bulbs on ebay for this but I'm not sure about the size. I know they are either T3, T4 or T5 bulbs....can anyone help and has any one done a DIY on this. I have pulled the units and it is a easy change is you get the bulb sizes....I'm sure at night everything will look brighter and better....
