Flashlight Head/Driver converted to Truck Aux lamps

Flashlight Modding and DIY Parts

Hello,

I have a pick-up truck that has two OEM 4” aux lights on the bumper that I want to convert using my unused flashlights of similar bezel diameter, but disregard the battery tube and use the 12vdc of the truck as power.

I need to know if it’s possible to convert a flashlight head and it’s driver for use in a vehicle 12vdc power as Auxiliary off-road lights?

Assuming the switch’s is Lo-Mid-High to turbo…or Ramping, can it be “programmed” to just stay in Turbo? ( or another mode )

I might not have covered all possible combinations and or power/connection potential problems that we might as well discuss here.

Thanks!!

As an example, I have 2 old Fenix TK70 that is powered by 4 nimh (4 x 1.5v) so I assume it’s 6v….if wired in series, then my 12vdc truck can power it. How about the switch’s L-M-H-Turbo setting?

Nice link…how about the light’s Driver which is multi-mode?

How can it be made to to be connected that it will only operate on a chosen “mode” each and everytime?

You would be able to activate the new aux lamps just for a few seconds before they start to heat up and reduce lumens.
I think you’d better go with real automotive lights made for that purpose.

True but if I’m thinking of just using the High mode, it would still last longer and throws a lot farther and usable throw as compared to the real automotive aux lights that are more very floody and near-field.

Btw, the TK70 I mentioned does not step-down from Turbo, and are de-domed. (If I choose this light)
