After trying various versions of LED T10 bulbs with plastic bases and different numbers of LEDs on the circuit board, I ended up trying these bulbs and didn't need to look any further. They fit in the license plate and cabin, have a cool white light - ideally, I would have preferred their color to be a bit warmer (they are roughly around 5500-6000K, not blue like some others).

Also, something important for experts - they have satisfactory CRI. In other words, they don't give off that "sickly" cool tone in whatever they illuminate.

In terms of brightness, they are great - much brighter than regular halogen bulbs and brighter than any I have tried. Also, their size is okay. They are slightly larger than regular halogen bulbs, but not dramatically larger.

As for durability, I can't comment as I have had them for six months without any issues, but they haven't reached a satisfactory number of operating hours yet. However, overall, they seem to be good quality and well-designed. Also, the silver part appears to be genuinely metallic, so I assume it will help with cooling - and the longevity of the LED.

Attention! When installing, be careful not to short-circuit anything with their metallic casing.
