weiXuan LED Festoon Light Bulb for Passenger Compartment Lighting, 27 mm/31 mm/36 mm/39 mm/41 mm, 12 V, 360 Degree Bulb, Warm White, 3000 K, for Passenger Compartment Lighting, Reading Lamps, Indoor Lighting, License Plate Light, Pack of 4

I needed these to replace the interior light in my Mazda MX5. Longer versions are easily found in every car parts shop but for some uncountable reason Mazda decided to fit these hard to find little short ones.The original was a tungsten bulb and I did not care if the replacement was tungsten or LED but these were cheap, they fit and most important they work perfectly without any negative effect on the car's electrical systems.

Lights good and the service

Really fast delivery. The bulbs are great I have found 42mm festoon bulbs difficult to come by and the only seller of them on the high street charges so much for 1 I could buy 6 of these. The bulbs are amazingly bright. I have put 1 in the boot of my Saab as the original had blown when I had brought the car. I will definitely buy some more later on.

Not as bright as the standard festoon lamps in the VW T4 these are replacing but will use much less power. Only time will tell re longevity how not overly re-assured that one bulb did not work out of the packet. Not a big issue as I needed three but would have been a pain if I was relying on all four!

All the bulbs work. They fit the holders well. They have a warm and bright light. Just what I wanted to replace the tungsten bulbs on my boat. Nothing bad to say about them.

The bulb works ok and is bright enough (you need to rotate the bulb in its holder to select the brightest position). However, when the switch is in the auto-switch mode the bulb stays on in a low flicker mode when the car auto turns the interior lights off after timing out. So they are always on and flicker of the auto-off mode. If you turn the switch to off, then of course the bulb goes out as there is no power at all. But this defeats the object of automatic lights.

These seem to match the original bulbs in everything except heat. Much cooler and hopefully longer lasting

Doing the job, and is not a fortune.
