Volvo V70 cargo area lamp Philips 12866

2001 Volvo V70 cargo area lamp (dome light bulb) Philips 12866. This lamp is also known as a Festoon style bulb. They come in all kinds of sizes - make sure you get one that is 41 mm long, 10W (10 watts). 12V (12 volts) of course.

I've also seen the part no. K25673 associated with them, but I have no idea if that is accurate.

I found them for a buck apiece at Totally Clean Marine (www.totallycleanmarine.com). Shipping was $6.95, so I got a few just to ease the pain.

Totally Clean Marine describes the bulb as follows:

Marine Light Bulbs

Festoon Lamps T-3

• 3,500 Life Hours
  
• Festoon Cap SV8.5-8
  
• 10mm Diameter

For all I know, it's available at the local auto parts store. However, I didn't feel like running around town looking for it.

Atlanta Light Bulbs sells them in lots of 10:
