Default H9 to H11 Bulb Conversion

Hi,
I have a question, I am considering of modifying a H9 Silverstar Ultra Bulbs to fit the H11 housing in my 2007 Camry HV. The current OEM bulbs really are bad and not bright enough, nor do I really want to do an HID conversion.

http://www.tsxclub.com/forums/showthread.php?t=15061

According to that site, the everything should fit after I just cut out the extra plastic tab in the connector of the bulb. However, it says the bulb uses an extra 10W of power..which I am concerned that it might be too much for the vehicle and melt the harness.

Update: actually, NVM, I guess there IS NO sort of H9 Silverstar available...could anyone suggest any other bulb that would do the trick? More light that looks "very white"?

Has anyone done something like this before and wouldn't mind sharing their experience?
Thanks, Paul

Paul,

a LOT of people have done this. It takes about 5 minutes to do a set of bulbs. As for the increased wattage, each bulb has a 15 amp fuse. The fuse should blow LONG before the wiring and that fuse is good for 180+ watts. Given a 12.6 volt nominal voltage that most car electronic systems are designed for, 65 watts would equal 5.2 amps. At 12 volts nominal, you would have 5.4 amps. The original 55 watt bulb has a rating of 4.4 amps and 4.6 amps figured as above.

Thank you!
Do you have any suggestions to bulbs that I could modify that is like the Silverstars? (now since I figured out they do not make an H9 filament!)

If you just want a good white light, buy any H9 bulb. They will be close to 4000k and a LOT whiter than your H11 bulbs. I would be hesitant to buy expensive bulbs as they will not last as long as the H9's. If you are a "money is no object" type of person, try finding Hella or Narva bulbs.

Note that Osram and Sylvania are the same bulb. In fact the Sylvania bulbs I am running are stamped "Osram" on the end and were found at my local Advanced Auto store. Another item to remember is that the "blue" tint on bulbs will reduce the available light. They might look "cool" or "like HID's" but will not give you the light that untinted bulbs will.
