I believe they're NLA from the manufacturer. Off the top of my head they're 12v "wheat grain" bulbs. 3mm and 40mA red/60mA blue with coloured silicone caps to change the colour. The sockets/holders are reusable.
Pop out the VSA switch cluster (push it out, there's a hole in the cubby below), take one bulb out and check the dimensions because it's been a hot minute since I had to replace one. DISCONNECT THE BATTERY or fuse #6 might pop and use a flathead to spin the bulb holder out of the switch body.
