I have a 2003 dark grey tl, and I was just wondering if anybody knows the bulb types for thé dome light and courtsy light. I know that the gauge cluster takes 75type bulbs. I'm going blue on this one.

 

welcome to the forum, You will find a little scrolling- use of search and cking the main DIY list yields tons of threads on nearly any subject concerning the TL
Try on your own before starting a new thread please~

there is a free owner book download from acura at Acura Owners Site | Exclusive Knowledge, Service, & Benefits
that will have every bulb listed

Im thinking I saw the complete bulb sheet among the diy list, go to bottom of opening page -after you logged in- bottom has several `Off Topic` threads you need to know!
