This is a short one: I open a Rimthin vehicle-lighting kit, take out the pair of bulbs and look over the housing and cooling hardware. The installation is still ahead of me at the end of the clip.

## Two bulbs and a built-in fan

The package includes the manual and two lights. I describe the housing as feeling like metal or aluminum and point out the fan built into the design.

That is what this video shows directly. I discuss a color-temperature figure and an advertised lifespan, but I do not measure the light output, run an endurance test or fit the bulbs into a vehicle.

## The fitment needs to be checked

There is a conflict in the source details: I call the kit H4 in the recording, while the title and description say HB4/9006. I also mix HID and LED terminology when talking through the hardware. Those names should not be treated as interchangeable confirmation of the exact product.

The original shopping link is below, but check the actual bulb and vehicle fitment rather than choosing from this title alone. I have not shown a beam-pattern, glare, weather-resistance or installed-road-use test here. For this first look, the useful view is the physical kit before installation.
