I think the "bulb" is an LED already so unless the LED is a previous generation it is likely all you are going to get as I"m thinking the batteries cannot drive it at a higher output? I just checked the battery is a 3V CR1025 lithium coin cell. I don't think you can do much about the battery at all as it likely underdrives the LED so unless you can find an LED that has a lower Vf that will fit in place of it you are out of luck

I had a chance to buy one of them on clearance once and when I saw the LED I was intrigued until I saw it took only 1 button cell. Lights with 3 lithium coin cells are what is used in keychain lights usually 2016s giving the LED 6v but the currrent draw cannot be maintained so the voltage drops under load and the LED although overdriven isn't at a critical range. 3V on a 3/5 mm LED is not going to give you a lot of lumens I'm guessing perhaps 5 maybe as high as 10 lumens with new batteries perhaps. If perhaps there is a lithium ion cell that size and you could fit a dropping resistor you could make it brighter but having to remove the cell and recharge is and buying a charge to do that safely all the cost and effort is not worth it for what the card has to begin with. I've had tiny lights using 3-4 AG1 batteries and they do put out decent light but dealing with the tiny batteries is a pain. I now have a minimum type/size of battery for smallest lights and that is 20XX or AAA although I think 10180 is probably a good option to consider.

I had one of these without a light and the plastic broke.
I'm sure it can be improved with an update but clearly this is a last-resort light and would never be used except in emergency. Mine is way less than 1Lm, probably 0.1 but likely needs a new battery - speaking of which, how do you replace it?
Anyway nowadays your phone is your backup flashlight and probably most people have their phone more often than a wallet. Still, might as well have a backup in wallet.

It should be at least 4-5 lumens if not 10 or so perhaps. I am clueless as to replacing it but I'm sure you can search for instructions online you may have to remove a screw to get to the battery.
