Greets.., since driving mostly at night for the past few months with the CIBIES housing, and the OSRAM 65/70w bulbs I only have one gripe. It comes with a qualification however, lol. Number one: The OSRAM is listed on the package, Item 64205.., as a BILUX H4 Off-Road bulb. Seems to me that OFF-ROAD is not DD on the street, therefore I guess one should figure not to expect longevity. Anyway, since the OSRAM/CIBIE's are a major improvement over OEM bulbs, (illuminating suicidal moose, etc.), it is by far the safest, brightest headlights over any other DD vehicle I've driven with OEM headlights over the past 32 years. The RUB: The OSRAM bulbs seem short lived. I have timed the hours, and on average they last only 120 hours of use before blinking out. (I have the harness upgrade too). I am on my third set since the installation I performed in the fall. (My headlights are always on for safety, day, or night). So, 120hrs. is a bit problematic, lol, changing them out on the snow, in the dark with a LED flashlight held between the teeth, lol, and ofcourse the temps down to minus degree f. temps, and in blowing snow lowering the wind chill factor, etc. Freak'in little screws, blah, blah. So, I drive 2 hours per day getting 60 days out of one set. Again, I'm on my third set.., as of last week. Hmmm... $$$ ... and in preparations, I have an extra OSRAM set ready to go when needed.
How many useful hours with the NARVA bulb's has anyone gotten? I will probably get some to find out 'fer myself anyways...
