The 10 Watt bulbs will draw about 0.7 Amps each (14V * 0.7A = 9.8W). The 5 Watt bulbs will draw about 0.35 Amps. Don't know what else is on the circuit, or what size fuse is blowing, but these are pretty small currents.

The current in light bulbs will be consideraby higher for a split second until it warms up. The resistance goes up with heat, which means the current goes down. This is why the lights in your house most oten blow when you first turn them on. Are the fuse regular automotive fuses? These should be able to take the higher current.

The "idiot light bulbs" in the 240 instrument panel are small bayonett bulbs. Do you know if these are the same. I can send you some. Just replaced the Instrument panel in my 240 today. The Spedo now works and I added tach.

Best of luck.
