Much improved dome lighting

Diameter of bulb terminals on the 4 cabin domes in 02 Odyssey are too small for fixture clamps. Requires either bending clamps or manufacturing collars for the terminals. I made collars from small hobby grade brass strips for the bulb terminals. Not a solution I'd recommend for everyone, but the result was satisfying. Plenty of interior light now with little chance of draining battery if accidentally left on.

Nice Light, wrong size

Honda accord takes a 38mm not a 42mm, was able to make it work after bending metal.

nice improvement but too small, too loose

Like the other owner, we have a 2004 Honday Odyssey. this bulb was listed as one of the correct replacement bulbs, but it is too small to fit snuggly in the clips in our vehicle for the interior dome lights. It's extremely loose in the clips, so it moves around as you drive. It turns or rotates in the clips so it doesn't always stay in place with the LEDs shining down, it can move to where the LEDs are not facing out at all. And it's so loose that it doesn't always make an electrical connection and the light can flash or not come on sometimes.

Rear dome light

very good illumination output. slightly longer than stock which required some minor modification to bulb mounts, also required orienting LED's to prevent partial shading by housing. Overall very good!
