light bulbs

["Ray Sinclair" <rsinc@foxinternet.net>]

I looked up the request for the technical data on the 158, 168 & 194 bulbs.
They are all physically interchangable. They are also all 12 volt based.
However the three bulbs do differ in amp draw and expected MTBF (lifespan)

158  .25 amp  500 hour MTBF
168  .35 amp  1500 hour MTBF
194  .27 amp  3500 hour MTBF
193  .33 amp  7500 hour MTBF (this are fleet service bulbs)
