I decided to install some H4 LEDs today. I have a MKII with has the England style Headlight with removable bulbs.

The original setup uses this boot around the bulb, but I don’t think I really need it. Not like I drive in the rain, but maybe keeps some dust out. Just looking for some verification / thoughts. Thanks!

My other (potential) issue is: I tested one, very bright, but has some flicker. Hoping when I do the other side, it goes away, or guess I’ll need some anti-flicker whatevers.
