I would recommend the covers...at least for the ones on the ceiling. A friend accidentally hit a bulb with a ladder he was bringing through the garage into the house, and the bulb burst, and the glass fragments landed all over his car.

One of my clients replaced their single garage light fixture (like you have) with a fixture that holds 4 bulbs. Between those multi-bulb fixtures, and their flourescent fixture, their garage is nice to work in for detailing.
