OK this is a bulb, it is not a part that needs an exact replacement part to work. So personally what I would do is measure the volts across the bulb socket & then measure the amps that a working bulb consumes. Ohms law says Volts multiplied by Amps should give you Watts. Then try anything that fits, that is the correct volts required, or of a slightly higher voltage & I would use very slightly above the watts required bulb too, if I had a bulb of the correct measured Voltage.
Like that, it is always going to be under stressed bulb, not over stressed one.
So what I am saying is. If you measure & do not get a manufacturer part. Err on the side of caution. Like that, what is the worst that can happen? I am no electronics expert, but my educated guess is, that if you work things out properly & err on the side of caution, the worst that can happen is that the bulb will be slightly dimmer.
When I helped a friend out on his old Uniden. I fitted a 12 volt rather than what my multimeter said, which was 8 volts across the bulbs socket. So the light was dimmer, but it has worked fine for about 3 years now, so he is happy.
