Okay this is the deal, I have a 2005 RR and my right low beam is out. I changed my bulb and still didn't work, after reading an earlier tread I'm thinking the igniter is the problem. I was also told that it could be the ballast, but IDK. Can someone let me know which is most likely to go out, the ballast or the igniter? What the difference between the two?

Okay but from my understanding to get to the them you have to disassemble the light totally.

You said you changed a bulb, but you don't know whether you have to disassemble the whole part? Or did you misunderstand? The recommendation isn't to change the igniter/ballast, it's to swap the blub. If the old or new left blub in the right side works, then it's not the bulb.

Actually I was suggesting swapping the ignitor over to test the ignitor. Aaking what is more common to go out doesn;t mean that is what went out. You are still going to have to test before purchasing unless you want to toss money at it and pray.

That's one way to do it but it's a lot less work to swap over the working bulb from the other side first... If it goes on then it's the bulb and you figured that out without pulling the ignitors.

Well yes, except that in his original post he states he already replaced the bulb. Although I guess he could have bought a duff bulb.

Hey guys I did swap bulbs, both bulbs work fine on the driver side neither worked on the passenger side. Maybe i should just try to swap the ballast first, because it seems to be on the back of the light unit and not inside. I really don't want to just toss money in the air and wish for a prayer, but I'm kind of afraid to take the entire light apart.

Yes, the ballast is more common to fail than the igniter. It is also easier to replace, although new ones are terribly expensive. I shopped EBay for mine, which was much cheaper. You have to remove the light assembly to reach the 3screws holding the right side ballast. The left side ballast can actually be removed with the light assembly in place, since the air filter is not in your way.

If you've not removed the left (USA passenger side) headlamp assembly before, please be very patient. After taking off all the air-filter assemblies (not difficult), you should put some strong duct tape on the top of your bumper, otherwise you will scratch it when you slide out the headlamp assembly. Use a very thin plastic thing to coax the duct tape under the headlamp, so that when you pull out the light, the duct tape stays put, and you slide the light over the duct tape. The most difficult thing about re-installing the light is to make sure the one flat 'clip' (almost 1" wide, bottom of light, slightly right of center) slots into the housing. This isn't too difficult, BUT you also have to make sure the headlamp-washer pipe fits through the headlamp assembly. The natural thing to do seems to be to slot the washer pipe through first, and then try to attach the clip. This didn't work with my car - it's almost as if the washer pipe is too far over to the left. The way I finally managed to do it is put the longest nail I could find into the washer-pipe, put the headlamp onto this, and 'bend' (push with left hand thumb) the nail to move the pipe over to the right slightly (1/4 inch), so that I could slot the bottom clip in properly, and at the same time move the pipe over enough to get it through the hole on the left side of the headlamp. Make sense? be careful removing the tape, and use a mild soap or detergent with soft cloth to remove any tape-residue.

Sorry to get back to you guys so late, but it was the ballast. I changed the the ballast and now I have light!! I spent about twenty-five minutes in all. Thanks for all the help... DIY is the way to go.

If you have to install one of these lamps again in the future, the cover on the bottom of the lamp that goes over the wiper post comes off. This makes installation much easier as you don't have to line up the wiper spline while trying to hit two holes you can't see below the lamp. If you understand what I'm telling you. The cover is 4 inches wide and it held on by a couple easily removed latches. Just pry gently with a screwdriver. As mentioned above, if you have to wait to get a bulb or ballast after diagnosing, move the working parts to the passenger (right) side. The driver lamp is much easier to R&I a second time! Good luck!!

I appear to have a similar but somewhat perplexing problem with my headlights.

My headlights will turn on when they want to. One day the DSide light will not come on but the other side works. Another day both work fine. The next day the other side won't turn on.

I've changed the bulbs several times with same results. Does anyone have ideas on how to troubleshoot?

yes its probably your ballast BUT it could also be a bad connection get some deoxit 100 and remove the connectors and ballasts from each lamp and put the deoxit on the connections then try it

Thanks Merlin. I'll try that tomorrow. I've also read that it could be the igniter. Hopefully, I won't spend hours trying to troubleshoot which of the 3 problems it is.

Oh yeah, both lights have been coming on the last two days. I thought when ballasts go bad they stop working completely? What about igniters, do they die or flicker for a while?

HATE TO REPOST:::

I have taken one of my headlight assemblies completely out to replace my igniter and I HAVE NO IDEA how to remove the shiny domes surrounding the bulbs to get to the igniter! ANY HELP PLEASE!

I've been following instructions in another thread here and the thread says, "no need to remove the silver unit, you can work around it." HUH?

How do I remove that single shiny piece? I've taken everything else off including the gray plastic surrounding silver. PLEASE HELP!​

The "work around" means bending the silver piece to get that last screw out and not being able to put it back in...
