I have a pair of DOT approved Hella H4s on my car. I am running the stock bulbs (I forget it's either 35W or 45W). I did not have any troubles with the rubber boot on the back, but I do have an 88. It all went together without any modification to any components.
The spec's I have for 9003 only list 55w for low beam... Sylvania, Hella, Donsbulbs.com etc all list 9003 60-65w high and 55w low. Stock HL bulbs for Fiero is 35w low beam.
Is confusion when H4 housings and bulbs are legal to use or not.
Some H4 parts are also HB2/9003 for meeting DOT(FMVSS) rules. Both
housings and bulbs must meet FMVSS rules or is not "street legal" in many states.
The housing and
bulb should be labeled w/ HB2 etc too. The Housing will have DOT HB2 on the front and have aiming bumps/points same as H6054.
H6054 and 9003 bulbs are legal at 65w high and 55w low. 100/55W, 100/80W, etc is only H4 bulbs and not street legal even tho will fit HB2 housings.
