I just saw a pair of Japanese aftermarket H4 RAZO headlights at my local auto shop. The headlights say that they only consume 55w or 60w (i'm pretty sure they're only 55w), but produce around 100w/110w of light. Are these lights compatible with my car? Or will they fry my harnesses? And secondly, are these even legal?

Have a look at the top of your headlights, there will be bulb ratings printed or stamped on there. Generally, and I mean GENERALLY! cr take H4 60/55W headlamp bulbs where im from meaning dual filaments. Ideally you want to take the bulb out and check the type and rating it is, (its printed on is it somewhere) and replace like for like ( ie if you have a n H4 55w 12v bulb adn thats what the oter one says it is your a go, otherwise get a clue or a good auto electrician. Cars are really not that complicateD!

Argh i just re-read that sheit and by 55 or 60w you mean its like a standard s high low beam bulb? well have a look or call your dealer and ask what type of hewad light bulb your car takes. We dont have matrix in NZ but its prob a corolla in disguise and toytas are awesome. Wlso Why are your headlight not bright enough being a brand new car?
