I have powered my grain of wheat bulbs in the Ben Ain steamer from the on-board radio receiver battery pack which is 4 x rechargeable AA's in a holder.
The current draw of the grain of wheat bulbs is so small that they should last an outing comfortably and then I simply recharge the pack.
I have 8 in so far and I have another few to fit yet on the navigation lights. They are all wired in parallel from a common switch so it couldn't be simpler. |
