Those Laser chains can be taken apart the button made out of two pieces of wire either soldered to two plates. This would allow you to put the trigger button anywhere and make it easier to push, even just picking it up cold make it come to life and if you wire the LED's to some Fiber Optics. you could really light it up, with one strong LED in a box, and different colored color plastic to make the Fiber Optics show variety using just one LED. My 450SL uses one Fiber Optic cable, and an Incandescent bulb, located in the center console, to light up the dash! It's a 1973 car. I think fiber Optcs are under used. People have to remember if you cut one, you have to polish the ends to get a lot of light back.
