Buying headlight bulbs for your car before you need them will save you an inconvenient (and if itā€™s at night or raining, potentially illegal) trip to the auto parts store, and with this $4 Amazon coupon, you might as well stock up.

Philips CrystalVision bulbs are the brightest bulbs the company offers, and come in tons of different sizes to fit most vehicles. Just note that you wonā€™t see the $4 discount until checkout, and donā€™t forget to do a little Googling to make sure youā€™re getting the right set.
