Default MB instrument cluster lighting

I am currently using LEDs to light the cluster. The OEM halogens burn pretty hot.

Trouble is of course that they are undimmable, but that's a small price to pay for
1-the 1 amp permanent saving in current drain.
2-a cooler dashboard.

The ones i used were pretty cheap, and can "flutter" a little, so i may try to spend a bit more on better quality bulbs later.
Any comments appreciated!

I thought some LEDs were dimmable?

I’ll take a look into that. Some are-but I don’t know if they are in this shape.

A quick internet search revealed many people with similar issues.
A canbus compliant led should resolve the issue of flickering.
While it may now draw close to the same current as canbus bulbs have resistors, I wonder
if the heat generated will also increase, as no current will
Be dissipated as light.

Anyone got any ideas? Maybe I can test a canbus compliant bulb and measure its temperature compared to a non compliant one.
