If you find the correct bulb you can try it,
however, LED bulbs are rather sensible to heat and if the housing don't provide adequate cooling the lamp will die.
As Hookup1 wrote, i would replace them with new LED lights, but not go for the cheapest ones.
I got some from WM for my Venture 34 and they fogged up and leaked after a year.
Dimmable ones (if available) would be best solution as some LED lights are crazy strong, so strong that at 100% output can be too strong.
I am in the same situation and the bow spreader light is normal bulb and too weak so i will try to upgrade the bulb as mine (at least the bow one) are recessed in the hard top.
