Q: This red LED brake light bulb is longer than my stock brake light bulb. Will it still fit? A: Yes. While it measures about 1.5 inches (38mm), the strobing LED 3rd brake light bulb will still fit in your cargo light housing. We've tested fitment on many different trucks including Ford, GMC, and Dodge to confirm that the LED brake lamp bulb will fit. If you've attempted to plug in the red LED bulb back but were unable to, it is because the wiring is too short. One workaround to this is to unplug the reverse light bulb socket on the side, which will give your LED brake light bulb clearance to be plugged in.
