H4 bulb install

Just got my hella e codes with h4 bulbs. I read something about wiping the bulb with alcohol but im not sure if that's necessary. I installed bulb with rubber gloves. I just don't want to burn out a bulb early.

The purpose of doing either of those, wiping the bulb with alcohol or wearing gloves, is simply to prevent oil from your fingertips from being deposited on the bulb's glass surface which can produce a hotspot on the bulb glass's surface and cause it to shatter. If you don't touch the bulb's glass with your bare fingers, it's not a problem.

When you have a choice, buy American.
