Do you mean stone breaks in glass headlights?

Basicly, you just try to create the best plug to patch the hole... it won't hide the damage to the lense. You need a clear, thick resin that cures fast. Clean around the hole and file or chip away any really thin or weak looking spots of the hole. Then dab resin behind and around the hole until you have a solid "plug" of resin. Finish like any other pit.

Some cars like Buicks and Cadillacs have headlights that pop out reallly easy. Then you can place the headlight face down and backfill the crater of the chip with resin from the inside. This looks much better than just plugging the hole, but it's not always possible. Btw, it can take a long time to cure a thick blob of resin like this.

Now, if you mean yellow weathered plactic heeadlights, thats another thing... I do that a lot more that I do holes.<img src=http://www.ezboard.com/images/emoticons/eek.gif ALT=":eek">
