Just did this, I have the same headlights.
Fastheadlights, talk to phil, he’s a forum member. d2s mini 4.0 retrofit+ hylux 35watt ballast + morimoto 35w 5500k
Somewhere around $300-$350 for everything, takes about 7 hours (thats how long it took me and I’ve never opened a headlight before) of labor (but mostly on a shop bench which is far less painful than wrenching.) and it’s headlight nirvana. Considerably more light and sharper beam pattern than any nice factory car I’ve been in, and I’ve been in lots of them.
35 watt is really bright and I’m happy I chose them over 55 watt. There are some rare occassions like rural roads at night I’d prefer the 55watts, but you’d be better off going with 35watts and adding a light bar.
