A really quick point on bulb classification – H1 and H7 bulbs are considered to be part of the same Group 1 classification of light. That still doesn’t mean they’re the same bulb. Group 1 includes H1, H3, H4, H7, H11, HB3 and HB4 lights and are the types of bulb used for headlights and fog lights.

Leaves a small clearance or creates a small interference. Assembly is possible using light force. Example uses in engineering: Driven bushes, armatures on shafts, etc.
