I installed a pair of H4 Osram Nightbreaker on my ex Vios. They really made a big difference. Lasted more than a year before I removed them when I sold the car. The last few nights with stock bulbs made me appreciate them more.

I don't drive much at night, so it may explain the longevity. I also read that thermal cycles shortens the life, hence before I switched them on I flashed my high beam (whenever possible) to warm them up before switching on the dipped beam.

RM130 including installation is not that bad, online pun RM100-plus iirc.
