The backlighting bulbs in a TB42 cluster I have are marked as A14 34 WL. Now I cant be sure if it is 3.4 as the markings are very faded But yes 5 watts is too bright for dash lighting. The dimmer is not made for higher amps either. Hope I have not caused you any further confusion.
None of the warning light globes have any ID marks on them.
The covered globes are designed to not reflect too brightly off the windows in the dark.
