I'm not familiar with the 150 light, so these are just general suggestions for any hole repair...As mentioned above, if you can get to the back of all the holes, then just switch to bolts with locknuts and washers. Use large enough washers to keep the nuts from crushing the fiberglass and don't overtighten. Bolts with locknuts should hold up much better than screws.
An alternative is to put a piece of tape on the back of the hole, fill it with epoxy, and redrill the hole for the screws.
If you can't get to the back side, then take some thickened epoxy and smear it inside the edge of the holes to make the hole smaller again (without getting epoxy on the top of the surface.
If you use either of the epoxy methods at a location where there is foam inside the fiberglass, then you'll want to clear out a small amount of foam from around the hole and fill it with epoxy. This will keep water from penetrating under the fiberglass. To clear out the foam you can put a bent nail or allen wrench in your drill, but for most small holes you can just use a bent nail and scrape out some foam by hand.
