Ok so, I am going to say hell yes this will do well for working in the dark! Here are some night pics, no flash.
Night shot of lights
Night shot of engine bay
The kit I got was this one from Diode Dynamics, Cool White.
No bouncing, pin switch is just above the fender top when hood is open and compresses easily on close. Simple install, I used an existing hole in the fender near battery. Few tries to get it to the close position I wanted.
Install for lights was easy, I uses some wire base mounts to zip tie to, and will run the wires under the insulation and mount more bases in there, have to go get some (along with christmas trees I lost ha)
Also need to cover the wires and mount them better by the hinge, but I got tired today.
Hope this helps!
