Our customers have asked for a 3rd brake light bulb as long as we've been in business, however we didn't want to offer one until it met the following two criteria.
We've incased the bulbs in a chrome housing so that the bulb blends right in with the cargo light housing, this way you don't have the unsightly look of an aftermarket bulb in your cargo housing. It retains the stock appearance while delivering a far from stock output!
