CEC Industries #112 Bulbs, 1.2 , 0.264 W, E10 Base, TL-3 shape (Box of 10)

These bulbs work just fine.

I noted that the power source was1.5v. I did not realize that means only one 1.5v battery. My application has two 1.5v batteries which causes bulb to burn out. I was primarily concerned with the E10 designation. The bulbs do fit!

If you have an older Snap-On Torqometer with the optional model suffix 'L' (TQ-250L, TQ-602AL, etc.) this is the lamp you need when your Duracell (etc.: Duracell >2016 are the worst offenders) battery has corroded the heck out of everything. It's the correct 1.2v (to operate with a single AA battery), E10 base, and it screws in, fits and operates perfectly.

To tell the truth, I don't know how long these bulbs last since it has been so long since we put it in. All I know is I got 10 bulbs for the same price I would have paid the dealer for 1 bulb. Have oodles to spare if the original replacement bulb wears out. It is identical in brightness to the original bulb.

After some research I found this light is an exact replacement for my older style dial type torque wrench. The light turns on when it should after the desired torque setting is reached.
