I replaced 4 regular incandescent bulbs in the included light box that houses my house/license plate. The brightness is significantly higher than the original bulbs, but since they are LEDs, the power consumption is actually lower. I even considered removing 2 lightbulbs to reduce the brightness. The original bulbs tended to burn out fairly quickly due to the extreme heat/cold in my area so all 4 replacement bulbs will still work through hot days, rainy days and days with strong wind recommendations. Installation is easy, these bulbs snap into place with just enough resistance to hold them securely, but not so much that you can't do it with one hand on the stairs (although the fixture itself can affect this more than the bulb) . )
