do the new bulbs pull more electricity?

can you show us pics?

can you describe the modding process?

 

Thank you for not PnP-ing..lol
Good way to use your head, will heat be an issue? I wouldn't expect it to be..just askin.
IIRC h11 is 55watt with a tip that's painted, and h9 is 65watt clear tip
So 10watt more
Edit: is the focal point the same on h9? Do you get the same beam pattern?

1. Yes, H9s pull more electricity. 55w for H11 vs 65w for H9.
2. Unfortunately, I don't have any. However, mark my words: the light is much brighter...and more importantly, much whiter.
3. Yes. I did not have any special tools. I used needle nose pliers to break off the top part of the notch, then used a really small, sharp, flat screw driver to "file" down the rest of it. Plugged right into the H11 socket with no issues at all.

I doubt heat will be a real issue; it's only 10W more, and it's not like there is any difference in the way they seat.

Oh, forgot to mention, there is good news for doing the modding. You do NOT have to cut/shave the small metal ring tab where the bulb sits in the socket. Our headlamps will accept it as is. So only thing you need to do is remove the small notch in the socket (the electrical socket) and you're good to go.

From the looks of it, the beam pattern is exactly the same. And there is no issue of blinding other drivers, because the Impala headlamps have a design that cuts off the bulb light at eye level so it doesn't annoy everyone.

 

You are aware that the H9 is just the high beam bulb for the car, right?

Basically what it sounds like you've done is modify the high beam bulb to fit in the low beam bulb's socket, so you have two sets of high beams.

Which means, yes, you probably will be blinding other drivers.

 

I know exactly what an H9 bulb is. It's the same bulb that's used in the highbeams. And no, it's not blinding other drivers.

Look at it this way. I spent $14 for a set of bulbs that give me at least 50% better output, rather than waste money on a set of Silverstars, Nighthawks, or whatever else.

It's a well accepted mod. The only time you will blind anyone is if your headlights are not aimed properly. If ever in doubt, DO NOT DO THIS MOD. It just so happens that mine are aimed just fine, so I've got no issues.

 

no matter what bulb you have in the low beam housing it will never be as bright at the high beam because there is a CAP over the bulb regardless if the tip is painted or not.

 

Good point; thanks for bringing that up. I can tell you it is certainly not as bright as the high beams. As a matter of fact, I can stare directly into the lowbeams with H9; I can't really do that with the highbeams.

 

So, is the goal *bright*? ~assuming~ he simply wanted more light on the road. Cap is there to not be annoying to traffic. Bulbs have it incase cars don't, Sylvania knows H11 is low beam, therefore painted tip bulbs.

Yes, the goal was not only to get brighter, but whiter. Again, there's only one real way to do that without wasting money. Comparing lumen output to something like a pair of Silverstar Ultras, which would set me back about $40.00, compared to a pair of H9s for $14.00, there's simply no match. The H9s blow it out of the water.

 

Hello all,


I am new to this forum and I recently installed this mod in my impala but I am wondering if you anyone has experiences any issues with heat using these bulbs in the long run.

 

FWIW: My OE driver's side low beam crapped out last week. I went to Wally World and picked up a set of Sylvania H11 XtraVision Halogens for less than $20. I swapped out the OE bulbs and was rewarded with improved downroad visibility. They "outshine" the original equipment and are 100% on-road legal.

 

^+1. XtraVisions are a great choice for brightness/longevity. I've used them for years.

 

I have used H9 bulbs in my headlight houseings and I love them, I just wish I could convert my high beams to properly use 9011 HIR bulbs 2300 to 2500 lumens like I did to my old car which used 9005 bulbs for the high beams. The bulb life I expect to be shorter but going from 1250 lumens to 2100 lumens is great and I see no excessive heat damage to the fixtures yet, with ease of changing exterior bulbs on these cars I am willing to change them more often. I am itching to try H9s in my fog lamps but i am worried about damaging them since they are projector fixtures. Anyone have any experience with this?
