Welcome to the ETS Forum Steelie,
I have had a few small squeeze LED Lights on my keys (MEC Turtle, Inova Micro-light) but all have turned on in my pocket.
I was in a gas station about 6 months ago and saw a cheap small imported single LED light that had a stiff metal clip attached. I used the light for a while attached by the clip but the head was not adjustable for height so I replaced it with a Pelican. I then removed the metal clip from the first light and attached the light to my keys, it has worked great for this purpose because to turn it on you have to push directly on a large sliding switch, therefore it does not turn on in my pocket.
I would in no way call this a tough, waterproof, high-tech light but so far it has worked fine.
I saw this light on the internet advertised as a low-priced but quality unit, but I now cannot find the site, I will keep looking.
There is no name on this cheap little light, I think I paid $3.00 but on the net they were less than that.
Mike
