Replace Low Beam (H11) Head Light Bulbs

Sat Feb 23, 2019 9:58 am

Wasn't able to find a HOWTO, this takes about 30 minutes if you know what you're doing, not quite as easy as some other vehicles but definitely don't need to take it to the dealership. Not sure if there are multiple types of headlamp assemblies but I have a 2012 USDM I-MiEV.

Tools Required
    philips head screwdriver
    flat head screwdriver
    10mm socket and wrench.
    optional: pop rivet removal tool

Instructions
    Each headlamp assembly is held in by three 10mm/philips head bolts. Remove the small plastic cover at the base of the windshield to expose the top bolt. This bolt only needs to be loosened, however it might be easier to just remove it completely. Your philips head screwdriver will need to have a normal/small shaft, a bit driver might be too big.

    The second bolt is under the hood on the top radiator support.

    The last one is the trickiest, you need to remove the the plastic pop rivet in the wheel well where the fender meets the front bumper, then pop the front bumper clips out by pulling up and away from the car.

    Remove the one wiring harness connector and wiggle the entire headlamp assembly forward and up. The top of the assembly has a small clip that might make it a little difficult to remove. You may also need to remove the plastic pop rivets on the top of the bumper and peel the bumper back slightly to remove the headlamp assembly.

    Unscrew the cap for the projector to access the low beam bulb. Might be a good idea to replace the high beams while you're in there. Also, definitely test the lights before putting everything back together.

    Installation is reverse of removal, I broke several of the pop rivets in the process but I was able to find a variety pack of generic ones for cheap online.

I used Diode Dynamics SL1 LED bulbs, which work very well with the I-MiEV projector housing and there is a sharp cutoff so as not to blind other drivers. This is not a promotion for this particular brand, but I found it was difficult to find specific information about what aftermarket solutions work well with the I-MiEV. I also don't want to have to replace these again any time soon, so hopefully they will last a little longer than the halogens.

Thanks so much, I just discovered today that one of my low-beam bulbs is out!

Should I replace both at the same time? Is the Diode Dynamics SL1 LED bulb a drop-in replacement? I drive with the low-beans on all the time, since our car doesn't have daytime running lights.

Hi Jenn, nice to hear from you again. Did a tiny bit of searching, and the Low Beam bulb is identified as H11 whereas the High Beam bulb is 9005.

Since you always drive with your low beams on, it actually might be worthwhile to put in LED bulbs from a longevity standpoint, although they seem a bit pricy. The H11 halogen bulb is 55W which means it draws around 4A. The Diode Dynamics H11 SL1 LED bulb draws about 1.6A, but touts itself as being superior in many respects.

https://www.diodedynamics.com/low-beam-led-headlight-for-2012-2018-mitsubishi-i.html

Scanning through Amazon I see that there are many less-expensive LED alternatives. At 1/2-hour minimum replacement time I'd be inclined to just stick in another halogen bulb to match the original and be done with it as saving a total of about 30W over the course of an hour is 0.030kWh compared to our nominal battery capacity of 16kWh is rather insignificant.

Do let us know what you end up doing and how difficult the installation turned out to be.

Hi Joe,

Thanks for the great advice! I'll be heading to the auto parts store tomorrow.

I looked on Amazon and found several different versions of H11 Halogen bulbs, each claiming to have better visibility than the next. However, they have different expected lifetimes (in hours), which isn't disclosed in the listings unless a reviewer posts a picture of the back of the package.

I'll let everyone know what I come up with.

The dual fog/running light housings used on the SE models are available on eBay for about $15 per pair - The exact same fixture fits many other cars and as long as the eBay listing says they'll fit a 2012 Mitsu iMiEV SE, then they will mount to your front bumper cover with 4 screws. You will also need to buy a pigtail with the plug to fit the housings, but they're cheap on eBay too

My Ford Transit Connect van came with fog lights but no DRL's, so I ordered a pair of the dual housings and they fit in place of my OEM Ford housings perfectly. I stuck with the halogen bulbs for the fog lights, but I installed LED's for the DRL's as several others here on the forum have done

A worthwhile mod for any handy person with an ES model that doesn't have fog or DRL lights

Well, I'm flummoxed. I loosened the top bolt, removed the second bolt, then released the clear plastic clip under the fender, but I'm not sure what to do from there. What/where are the front bumper clips and where is the third bolt?

Thanks for any further advice!

I just found some videos on you tube that I think will help answer my questions.

I'm still stuck on "remove the wiring harness connector" - is there a trick to it? I can't separate the two halves. Someone posted the same question on the you tube video as well.
