4xAAA direct drive?

I have a cheap-o 4x AAA light with on-4hz strobe.

Only problem is the driver is dead so its outputing around 10 mah. Its really nice and low, just useless as a bike light. So my question is this. Is 4x 1.5v AAA safe for direct drive? Or should I just stick a wire between two contacts? The battery holder has the switch attached to it so I can't get rid of that. I don't have rechargeable AAAs, only AA, 14500s, 18650s and rcr123s. lol

I don't really feel like getting a driver from dx... Previous attempt at putting a drive in a different light: DX driver came DOA and I waited too long to get an RMA. Not gonna order another of the same to get an RMA on the first. This isn't walmart we're talking about.

What LED are you driving?
Or are you using standard 5mm LED's?

I typically drive cheap 5mm LEDs with 5 or 6 volts. They are damn near free, so I drive them hard, at about 100mA instead of 20mA.

Its got an R2 in it. I was thinking that using 4x1.5 might be OK because the current is limited by internal resistance.
