Compared to Australia, specialist shops seem harder to locate, e.g., A/C, radiator, exhaust, or electrics. Most where I live are either general mechanics or tyre shops, with a battery display outside.
All my auto-electrician did was to swap the factory standard bulbs for some better Philips halogen bulbs he knew would improve lighting coverage without blinding oncoming traffic. There must be some Toyota/ Toyota Vios forums on the web where others have upgraded their lights.
Years ago I had a Suzuki Baleno rental. As soon as you went outside of town, the high beams were pathetic. Being only a small car, it may have been designed for city use.
When you change bulbs, they should check the alignment for you.
