Hi folks. I have to replace an SX-636 dial pointer light, which is an 8v 50ma bulb. I have none of those here, but I have some 6.5v 70mA bulbs. Can I just stick a 20-ohm or so dropping resistor in-line and use one? I swapped the dial lights to LEDs so the extra current draw shouldn't be an issue. I have a ton of the 6.5v bulbs and have the 636 open now, so I'd prefer not to wait a week to get an 8v bulb.
