Ah i figured it out, so i have several eb1-c 200 lumens 1 eb1-c 300 lumens and 2 eb2-c 500 lumens. On the heads they're marked 1 of 3 ways: hot surface, hot surface/qr code with a short serial number or hot surface/qr code with a short serial number but with a -c on the end. The new gas pedal switch works as a monentary/ constant on only with the heads with the -c on them, the other 2 types of heads it works like how the gas pedal is suppose to work. Very interesting
Edit: arg i thought i was on to something but this theory isnt true for my silver eb1 or my 2 e2d defender ultras hmmm weird. There must be some circuitry in certain heads that reconizes the gas pedal
