bulb failure position light

used bulb no. 1073 (got a box of 10 off eBay). Volvo S60, V70

update: the 1073 bulb is too big. The base is correct, but the glass portion of the bulb has a diameter that is too large to fit into the opening in the lens assembly.

further update: apparently the correct bulb is Wagner part no. 17171 (aka BP17171). http://www.donsbulbs.com/ has great info, but ridiculous prices. Anyway, the following is from DonsBulbs.com:

R5W 12V 5W BA15S ECE( R5W/12V/5W/BA15S ECE )
also known as: I 12V 5W BA15S TUBE( I/12V/5W/BA15S/TUBE )
price per bulb: $6.80 (are you crazy Don?)

I 12V 5W BA15S TUBE bulb specifications:
category:Incandescent
volt: 12
amp: 0.417
watt: 5
base: BA15s - Single Contact Candelabra Bayonet (or S.C.Bayonet)

fil.res.: 28.8 ohm
m.o.l.: 1.47 inch (37.3MM)
l.c.l.: 0.748 inch (19MM)
burn pos: burn lamp in ANY position
cri: 99
d.hours: 200


In contrast, donsbulbs.com has this to say about the 1073 bulb:

1073
also known as: 1073 12.8V 1.8A USA( 1073/12.8V/1.8A USA )
price per bulb: $6.20

1073 12.8V 1.8A USA bulb specifications:
category: Miniature
volt: 12.8
amp: 1.8
watt: 23
base: BA15s - Single Contact Candelabra Bayonet (or S.C.Bayonet)
glass: S8
filament: C6
fil.res.: 7.11 ohm
m.o.l.: 2 inch (50.8MM)
l.c.l.: 1.25 inch (31.8MM)
i.lumens: 402
cp: 32
d.hours: 200

So, it's apparent that the 1073 is a 21 watt bulb, whereas the bulb needed is 5 watts. I'll try the 17171...


****Update (this is really a prologue):

The incandescent bulbs discussed above are to replace some absolute cr*p LED bulbs that I bought on eBay from virtualvillage-usa. The seller was actually very good in terms of customer service, even sending me free replacements for my first set of failed LED bulbs. However, their customer service can't offset the fact that the product is completely worthless, with bulb life being measured in days (for some) to weeks (for most), with only one bulb or two bulbs out of the eight that I installed lasting for more than two months. Clearly an inferior product, unfortunately.
