12v led with strobe

I have a 12v flashlight with a xenon bulb and want to replace it with an led module with strobe and memory. I want the brightest light possible and fast strobe by memory I mean it stays at the last setting when turned back on. It has the same size reflector as most tactical lights 26.5mm I think.

Thank you for any help.

Is there no one to help an old fool or did I post in the wrong forum.

Tell us more about the light .

Brand ?

Picture ?

I bought the light from sports mans warehouse years ago and there is no marking on the light. I have no way of posting pictures. It takes four 123 batteries for the xenon bulb. I have a cree r2 bulb in it right now but I have to use a spacer with 3 123 batteries as the led is only rated to approximately to 9 volts, I cold use the longer rechargeable batteries ( I forget the number) but I don,t have good luck with rechargeable. So I am looking for a led module that will take 12v. I found one 5 mode cree (forgot the number again) but was wondering if there are other options out there. Not havening much luck on google. I don,t care if it is a 5 mode or not but do want the strobe.
