Mex's observations indicate these are not a good choice as they get too hot. They were designed as daytime running lights and would likely see adequate airflow to keep them cool in such usage, but retasked as interior lighting could be a waste of money and time to wire them up.
The ones I have appear identical to those he linked, but who knows how they match up. I've not tested mine for temperature, but they have not failed.
When my back doors are closed there is no Airflow to them, and they shine into the door 5mm away. the velcro keeps the metal backing from allowing the door frame to act as a heatsink. When back door is closed but side door is opened, and I have headlight knob not rotated all the way CW, the lights are illuminated.
I would guess mine have several dozen accumulated hours over the last year where they were lit with no ventilation and they still work.
it appears the ones Mex has tested are likely brighter, driven harder and hotter and would not survive in the location I use mine.
So buyer beware. You do not know what you buy will actually work in the intended usage, for long
