So what are most people using to make the 9011 bulbs fit more snugly? There was a mention of dialectic grease, any other options? Also I saw a thread where someone made a computer drawing of the dimensions to trim the tabs on the bulbs. I can’t recall if it was for 9011 fitment in the low beam side. If someone has the trimming dimensions that would be great. Thanks

This is a very easy fit. Trim the tab and cut the slide. Just keep the stock bulb for reference. The 9011 fits fine
So maybe those with fitment issues trimmed a little too much off?
Possibly. I haven't read through this entire thread. I just ordered some 9011 bulbs and looked at what the difference was and trimmed it. I used the oring from the original and slid it over the 9011. They locked right in.
Don't know what you have done so far, but most people re-use the o-ring from the stock bulb and add it to the HIR bulb (so it has 2 o-rings) and then it fits just fine.
I haven’t done anything yet. Just some reading and thinking. Are the low and high sides different in terms of the tab trimming needed or are they same? I guess I’m asking if I keep pre trimmed spares can they work for both low and high sides. Thanks
Just completed this, 4x 9011 HIR. Nice improvement over stock for 15min of work!
I only have it on the lowbeams, but huge improvement, agreed.
I did the sleep harness on my 91, it's a real pain because my battery is on the passenger side so it was hard to find a place for all the relays. Also I ordered new bulbs from slee for the high beams and they fit like crap, as in not tight in the socket. Now you got me thinking I should just remove it and update the low beam bulbs next.
Please dont beat me up to much for this stupid question. I dont understand the purpose of putting 9011's in all four locations does. Dont the high and low sockets work indpendently? Or when the hi9gh beams are turned on all four bulbs are on? I trying to decide if I get 9011 and 9012 or just 9011's.
When the high beams are on, all four bulbs are lit up.
The purpose of putting the 9011's in all 4 holes is that your low beams are a bit brighter than using 9012's in the low beam spot. And when the highs are on, well they're a little brighter then, too.

Ok. So 4-9011's it is. Ujust want to clairify no need to replace harness for this corrct? And only the low beam 9011's will need triming correct?
I trimmed all four bulbs to fit.
Correct, no additional wiring needed. And both high and low bulbs will need a little trimming. I have done both my rigs and find a small pair of diagonal cutters snip it right off. Remember, you can always cut more so be conservative with the trim.
Ok sounds good. Thanks for the help. Looking forward to getting and installing them.
Be sure to search and find a diagram on the trimming. It's a piece of cake with the wire cutters as noted. Some people have suggested cutting with a saw blade or filing, which I do not recommend. Those methods produce extreme stress on the delicate filaments of a bulb and you're probably significantly shortening the life at best. Just simple snipping with wire cutters works a treat. Once you have done this upgrade, you'll laugh at how simple it is and that you were concerned. Enjoy - superb light output awaits.

I used some small wire cutters. Just eyeballed it. Its super simple to do.
Ok. I feel like an idiot for even asking questions on this now that I've done it. It was so easy. Thanks for the help and patience
Hi from Europe-- I can only find Osram (made in germany) and Vosla 9011 and 9012 available. Anyone had any experience with Osram (they are also an OEM mfg)? Having read this excellent thread looks like Vosla is the old Philips. As I am running Right hand drive lights here in the UK and frequently drive on the Continent (left hand side-- my truck is Swiss left hand drive '06 HDJ100), does anyone have any experience how wide the beam pattern is compared with OEM bulbs-- I have PIAA in there now? I am assuming even though I can dip beams manually, I will need to put a 'blinder template' on the front lens given lumen upgrade of HIR. Thanks
