Changing headlight bulbs

Try to avoid touching the headlight bulbs when changing car headlights. It’s like this. Most bulbs made for car headlights are filled with halogen. If you handle the glass with your bare hands, chances are you will leave invisible trace amounts of grease and oil on the glass of the headlights (oohh…. very CSI!). When the headlights are turned on, the bulb heats up and the traces of grease and oil on the glass will get hotter which eventually will cause the glass to crack. So when changing headlight bulbs, hold them at the metal base or use clean gloves.
