I have open beams in my car, I know they use H4's but I am wondering.. 9003ST bulbs looks exactly the same. Are they the same as H4's? I have looked into the tech info on the Sylvania Silverstar and the properties are exactly the same. The reason I am asking is because my mother bought my some new bulbs for X-mas (wrong ones but it's the thought that counts
)
The place she got the bulbs from does not have any H4 bulbs in stock nor carries them in H4. (why I have no clue) but they do carry the 9003ST bulb.
Any bulb men out there that can help me out it would be great thanks guys![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)

Same bulbs, fits the same lights. Personally, I think the design of the headlight lens and reflector makes a bigger difference than the bulbs. Be sure to make new wiring with relays to get the most out of those bulbs.
