Do you just want to put a newer brighter bulb in it , or would you like the cause of it being on , to be diagnosed and repaired so the light only comes on for the 'self-check' and then goes off ?(read that as goofy , not malicious) Some auto parts stores will read the codes for you for free.(serious) If you have one available near you do that and WRITE the codes down or ask for a print-out if that's an option , then post the codes so we can help.(really serious)
