Interesting fit with the brass bars. How's the heat conduction through the brass? What is it's copper content?
That old aluminium heatsink looks like it is a good fit.
Have you put any small 1 to 2mm diameter holes in the plastic roof mounted housing to aid in airflow and allow for heat to escape?

How long do you plan on turning the light on continuously in it's present configuration? 5 minutes? 15 minutes?

Are you going to work on a map light next?

I don't know, just some random brass scrap I had.

Yes and no. It took some work on the mill to get it to fit.

No, but that's a good idea.

That's the beauty of the dimmer, you can leave it on medium for regular use. Turn it down low for a task lighting at night without blinding the driver. Turn it up high and find misplaced or dropped items.

Choose a brightness that is appropriate for the task.

Very cool mod! :thumbsup:

So, are you thinking about a bright map light next or a lower power but helpful rural use light project?

I'm not sure I understand your question.

I have no idea what the next project will be.

This is a perfect use for high cri p4's, nice job on the mod.


The red in your seat belt clips shows up nicely.

I can never get the white balance setting on my camera quite right. In reality the light is not quite that warm. In fact it's a bit too cool for my liking. I'm sort of wishing I had used the 3000k emitters, but I've gotta use up these 4000k's on something.
