Putting a bright light on things
I purchased a 44mm bulb as the chart stated, my vehicle required, I was so happy when the bulbs arrived at my home. I quickly tried to install them in my vehicle, only to discover, they were the wrong bulbs, my vehicle requires a 42mm bulb, I called the company, return the original purchased bulbs with no refund problems, purchased the 42mm bulbs, and they are very nice, very bright, crisp clean look, I love them, I will continue shopping with this company, I give them and their service, 5 stars
Fits well into original 578 bulb housing
In my 2001 Ford F150 Supercrew, this bulb fits easily into all five 578 interior dome and map light slots. Bright but not too bright. Warm color works well for interior. The contacts at ends engage well with contact clips in the housing and the circuit board does not interfere with the clips or with housing.
Try this one rather than the 4410 LED from the vehicle lookup. On my truck the 4410 LED circuit board is too long to fit between contact clips.
Honda Accord Dome Light
Wanted to replace the dome light in my Honda Accord, so I took a risk with this over sized light since I really wanted the extra lumens. The board the LEDs are mounted to ended up hitting the clips on the base, so grabbed the Dremel tool and ground off a little bit of metal from the clips. Don't grind the board!!! You'l damage the ICs! A few minutes later, the fit was spot on and the cabin was flooded with bright light. Caution - don't look into the light when you turn it on - they're that bright!
Good LED replacement dome light
These were purchased to replace the standard dome light bulbs in a Sprinter Crew Van to reduce electrical current draw. They fit exactly like OEM bulbs, are slightly brighter and shine a natural color tone. No problem with "after glow" or bulb-out indicators which I'd read about as a problem with other LED replacements. Purchase was easy and delivery was prompt.
