I did this last night... then when pulling them out to temporarily put the stock bulbs back in, 2 of the 3 tabs on one of the bulbs cracked right off. Needless to say, I'm going to look for a replacement or refund. The latter being likely what I'll push for. Doubt I'll buy from them again

Have their 35w 5k kit in my MR2 and FRS. Almost three years old in the MR2 and zero problems.

I've used DDM tuning, the kit for my FRS was great.. The kit for my moms new sportage would not work properly .. It would just flash for a bit then flicker... I swapped out my ballast with my moms kit worked flawless.. And my moms ballast work in my car.. So it's all good... Now if you want quality.. Go with "The retrofit source" I bought the retrofit mini h1 kit and its night and day difference from the stock projectors... Some things just need to pay more for the quality

another possibility is that the lamps just need to be adjusted. the manual for our car is somewhere on the forum and in it explains how to adjust your headlights. when i installed my hid kit the beam i got was much higher than with my stock bulbs so i had to adjust the lamps to point them lower/closer to where the factory line was. it's pretty straightforward to do since all you need is a flat head. find the little gears on the headlights and start turning them in a particular direction until you get them where you want. i believe each light should have two gears. one for vertical and one for horizontal. it's at least worth looking into. maybe it got turned all crazy in the factory?

edit: unless that's what you meant by you tried to adjust them. sorry i reread your post and saw that you did try to adjust. *shrug*
