What difference are they between a H4 and a H6.
I didn't bother with shims, as a few people had had issues with them.
If you want a set of shims get in contact with Scarp, as he has a set of shims on his shed wall.
You guessed it, he didn't use them either.
The standard h4's i bought are 45 deg bottom tabs.
A bit of back reading on the forum and I had another shot
I cut the two bottom tabs of one and they just whant to twist inside the holder from side to side.
Then just bent the tabs on the next bulb but not happy with how they sit.
I will speak with my local auto parts store for availability of the Narva H6 bulbs on tuesday.
They look an exact match as they have higher tabs so hoping they just fall straight in.
