When fitting replacement or upgraded headlamp bulbs, its important that no grease from the
fingers is allowed to contaminate the glass envelope of the bulb. Grease will cause hot
spots, resulting in black marks and premature failure of bulbs due to overheating. If you
touch the glass envelope, use methalated spirits or IPA cleaning fluid to fully remove any
grease reside.
