H11 to H9 switch

**rudeboi0427** · 09-05-2012 06:12 AM

So iv been doing some searching on this and want to do it, but I'm just curious which company is the better one. The brightest and long lived. I see some nice pics of how bright they turn out, but they never put what bulb they used. Thanks

I just upgraded my bulbs to GE Nighhawks and Philips VisionPlus and they work great, much brighter than OEM. I don't see a need (for me at least) to go to H9's.

Yea that's what I was doing and heard about the h9 and how much brighter they looked. But your saying those nighthawks are good?

I could only get the nighthawks for the high beams, the philips are my low beams. They are great, much better. Just make sure you don't get the platinum ones.

damn, i just linked this in another thread.

H11 to H9 conversion. DIY with temps - NASIOC

the issue is the H9's but out almost twice the lumens that the H11's put out. to my understanding, the H9's are high beam bulbs that can be slightly modified to fit the H11 sockets.

no issues with glare or getting flashed from oncoming motorists. -i challenge anyone to actually do the swap to know what i mean.

i could have spent $30+ on "super" H11's of various brands and flavors... ended up with a pair from headlight bulbs.com (hyper whites) and love them. -that said, most of the people on the various forums seem perfectly happy with the $10 H9's from Sylvania or Phillips.

the only downside is a shorter bulb life (2 - 3 years tops)...

the thread linked above has pictures towards the end of my car as well (posts 141 and 142).

yep .. have to agree with you chet .. this was my first mod on my 12 wrx..
the stock low beams are dangerous at best .. check the spec's.. I did and
thats why I like

I just did this tonight, but instead of filing, I just got a solder tip and melted the extra plastic away n then pulled it out with tweezers. The headlights work fine, big improvement over the h11. This should work right? My car won't blow up would it? The extra part is just extra plastic?

Also, I accidentally touched the bulb slightly with my fingers, anyone know how bad that is or anyway I can clean it off? I'm thinking of isopropyanol.. anyone tried?
