Replacement Bulbs

Hey guys,
In the climate control unit of my MR2, there are 2 bulbs which burnt out. Does anybody know which replacement bulbs I need to buy? I'm not talking about the LED's that light up the buttons when they are on. These bulbs light up the actual climate control unit.

There are no markings on the bulb, and the bulb has 2 wires which wrap around the socket base.

I went to my local electronic store and in their catalog they call something similar to those labeled as: "T1 3/4 wire bipin", and the only ones they have are rated at 14 volts.

Will this one do? Is putting a 14 volt replacement bulb acceptable (will it burn out faster, will it be dimmer than the old one, etc).

I would hate to have it burn out after removing that unit (pain in the ass).

Thanks
