that's 'cause you use reinhard tonemapping... (reinhard auto exposures your pic as good as possible, it tries to avoid pure black and pure white pixels)

two ways to get arround that:
1) make your emitter weaker (don't turn it completely off, but make it weaker)
2) use linear tonemapping - a bit harder to use than reinhard, but as long as you export the igi and you can post edit the tonemapping in violet, you shouldn't have troubles with that

its an tonemapping issue!

Black Body is sooooo bright that much more bright could not go!
So use efficiacy_scale for your meshlights, but finding the right values is a try & error work.

You also could try to reduce your Black_body gain value massively!

Just raise Env map gain

Smartden hit the nail on the head.

Just increase your Env map gain. by 10x or more

5 or 7 should be enough too. Just try out!

Try both, emitters and EXR. With emitter you can get good shadows and EXR give you nice revlections

I guess its better with only emitters. BUT (and its a big but) only if you add some other low power emitters (perhaps 2) around the model, i mean like long rectangular boxes so that you dont get 2 funky shadows. that way, the scene will still be bright, but you will still see the headlamp thing.

-OR-
you could go for a nice smokey.foggy effect and put the whole thing in a giant SSS cube and see the headlamp from the model illuminate a cone of light, that'd be pretty kewl

mind uploading the blend file? id like to take a closer look at that thing, looks interesting
