Miniture lamps side marker

[dherv10@xxxx]

Group, Well I might as well go around the car. The side marker lamps 
original from the factory are 12 volt 4 watt Thorn brand. Weird #'s 
and a weird style name. I'm not familier with there style # they use 
and it isn't in the catalog Sylvania/Osram. They are 12 volt and most 
of the 12 volt bulbs have a 200 or 300 hour life rating. If you go to 
the 14 volt bulb,G 31/2 style glass which is the small round glass. 
Then #53 14.4 volt 0.12 amps 1000 hr life rating will work just fine 
in all outer marker holders. 
If you want the longer glass style which is T-31/4, Mini Bayonet, 
then the 1816,1815,1891,1889,1893 or 1892. They will all fit and have 
different hr's of life and different current draw. 1893 has the 
highest current draw at 0.33 amps and 2500 hr's life rating.
Hope this help
