What is the difference between h1 and h7 bulbs.
H7 bulbs on the other hand turn on when the car is being used in the regular low beam setting.
H1 bulbs are used to power the brighter high beam headlight that illuminates the surroundings over a long range.
My brother bought headlight upgrades for his 98 bmw 3 series.
They light up a narrower and shorter range which is adequate for daily driving.
If you re not sure which fitting you need you can check your owner s manual or use the bulb finder on this page.
The h1 bulbs fitted the headlights but im just wondering why they gave him the h7 bulbs.
9007 h1 h7 etc are all just the connector types and have nothing to do with the brightness of the bulb.
Generally they are not interchangable since housings are designed according to the mounting bases which are different and the filiment length.
Whilst an h1 and a h7 bulb may look the same in terms of light output an h7 bulb won t fit into a socket for an h1 bulb.
