If you can find a small 16 ohm resistor, just tack it in there being sure it isn't shorting to another track. It doesn't have to be an SMD

Here's some White LED wedge lights that I have for my 850 instrument cluster.

There's four of them and I have not tried them yet. They offer some benefits, less current draw, not prone to blowing out up to 16 Volts, way more immune to shock and vibration, and long life, which is always nice in the instrument cluster. LEDs make filament bulbs obsolete mostly, and they might be less expensive.

They come in many other colors.

Maybe the Blue LEDs will do the trick for you?

There's two types of sockets for the T10 wedge: one has the bare wires bent over a plastic base, and that arrangement didn't like the red door markers socket in the 850. The more reliable T10 base uses a PC board and works fine.

There's quite a selection there, be careful that you don't over do it since a
5W LED will most likely be way too bright maybe this one might be suitable?
They're cheap enough to give em a shot.

You might find the 1.25W too bright as well?

The LEDs are polarized so you can install them backwards.
I don't know if they are dimmable.

Post back with any good results.
