This may sound like a simple problem pero feedback would be appreciated..
My '96 Lancer GLxi when on park light, masmalakas ang intesity ng right bulb kaysa left. I do not recall ever changing either one of them. What should I do? Bumili ng bagong pair or park lights or is there something wrong with the electricals? Thanks.

Go the cheapest route first, take off both light bulbs and test a single bulb in both sockets, if the light emitted is the same, then it's the bulb that has the problem, if iba ang intensity, then wiring may problem.

an incandescent lamp sometimes tend to be brighter when it is near the end of its life. baka malapit na mapundi kaya mas maliwanag siya.
