The passenger side lowbeam bulb has blown in my Celica. I bought a suitable new bulb from SCA but can't figure out how to put it in. Most of what I've been able to find on the internet is either for other gens or say that the whole headlight has to be replaced (which I don't really want to do). Can any one give instructions or direct me to some instructions on how to replace just the bulb? Thanks :)
