only hella /phillips ballasts ( they are the same made by phillips rebradned for hella,others may think different but have no clue)
the earlier ones with built in ignitors seem to preform flawlessly over time which would be the 97-2000 style ones that i use also after having 3 types it is the best hands down with zero problems
always add a seperate ground to the ballast cases have them properly sealed from water and use bulbs which are oem style of 4000 to 5300k colour for output and longevity never buy a bulb with tinted blue lenses for the purple colour.
Buy a bulb with the oem d2r or d2s name on it and a good base adapter for your fitment as needed such as mine is 9006
don't buy them if you have any electrical problems as the ballasts are sensative to voltage spikes and drops(especially) if your alternator is not up to snuff replace ti before installing it.
300-500 is the price range for a new system
this is a good kit with external ignitors but oem to toyota
this is a style of crappy bulbs
this is the styles i have in both of my personal cars and love them as does anyone else i know with them for reliability, they only have problems if they use crappy bulbs and cut off the red end harness which is oem for almost every manufacturer
good luck lots of choices but few are quality
taiwan quality ones are bull !Removed! you will be replacing bulbs and ballasts like you have money to waste.
i have 2 cars and 7 ballasts with 8 bulbs ,case in point
