How To Tell If Your LED Bulb Can Fit Into a Housing

When it comes to core bulb sizes and their derivatives, it’s good to know that these bulbs can fit into the same housing. These bulbs include:

9005 –> H10 (9145, 9155, 9150, 9140)
H11 –> H8 H9
880 –> 886, 889, 892, 893, 890, 862, 881, 884, 885. 894, 898, 899

Bulbs to the left of the arrow will be able to fit into the housing of their respective core bulbs to the right. This demonstration is based on the 9005 bulb with the H10 core.

The 9005 bulb is a derivative of the core H10 bulb, meaning that bulbs sizes such as the 9005, 9145, 9155, 9150, 9140 can fit into the H10 housing. At first glance, it may appear that the H10 bulb has tabs that cannot fit into the stock housing. Actually, the bulb can still fit into the housing with a little bit of twisting and maneuvering.

Start with the smaller tab and tilt it a little in order to maneuver and wiggle it into the housing. Twist the bulb clockwise to lock it into the housing.

Proceed to lock the other larger tabs in using the same method.

Push down and twist to secure.

The same concept applies to other bulbs as well, as long as they are a derivative of their core bulb sizes.
