Update for Lighting FAQ - HIR part# (1 Viewer)

[Bruneti]

a. You local John Deere Dealer. They are available under part # is AH162232 and the price each was $28.55. Note that these are only low beam replacements, no high beam is available and you will have to trim the tab as described above.

When ordering HIR low beam bulbs at my local John Deere dealer, I gave them the AH162232 part number from the FAQ. They looked it up, and told me there was a new part# for that item. I nervously ordered it, fearing that I may not get the HIR2 that I expected. However I can now confirm that it is the correct part!

Info from Bulb Base:
Toshiba Japan
12V 55W
HIR2

Old John Deere P/N: AH162232 Price $28.55 ea (per faq)
New John Deere P/N: AH211917 Price $26.55 ea


Could somebody please update the FAQ?

Addition made with old part # still listed thank you for the update and thanks for using the FAQ thats what its there for, and people like Cary and others do alot of research to bring that info to other board members.

Nice information. It is worth noting that the new bulb is the superior Toshiba/Harrison bulb.

Bruneti,

Thanks. I just ordered a pair. The parts guys said they'd be in tomorrow($26.75 each for me).

Are you running an upgraded harness (Slee or home grown) or are you running a stock system?

Reading the FAQ, I get the idea that 55w of draw is 55w of draw regardless of the lumens produced. These shouldn't be any worse on the stock system than the stock 55w bulbs, I think. Is that right?

Anyhow, I think an upgraded harness is a good idea, if only to eliminate the current running through the switch. I'm tempted to buy the Slee one to save the effort, although I built a great setup in my former rally car (4 regular lights - 2 hi 2 low, plus 4 hella lights - 2 wide angle + 2 pencil beam - for night stages). Not really tough to do, but sure is easier to pick up the phone and order it all at once - done and done right by a pro.

Although you don't need an upgraded wiring harness for the HIR lights (you are correct in your assumption), it is very nicely made and will add a little more power to the bulbs, as you might expect.

The harness was originally designed for anyone wanting to run 80W bulbs, but, as the Hella 80W bulb quality went into the crapper, people have moved on to the HIR's.

You are correct, 55 watts of draw is 55 watts. The HIR's are more efficient, netting a higher lumen per watt than the traditional bulbs (This is similar to how florecent puts out more light per watt than an incadecent bulb).

The wiring harness is still a good idea because it limits voltage drop. A .5 volt drop at the light reduces output approx 25%.

Mine came in yesterday, picked them up today. They are also the Toshiba HIR2.

John Deere dealership had to order them, but they were a lot less expensive than the other HIR2 suppliers in the FAQ that Cary posted.

Now to figure out how to mod the tab and get them in the rig. The low beams sure need it.

A dremel is your buddy!

Ryan,

Cool, I've got a dremel.

The FAQ mentions:

"The HIR bulbs have a double-wide top ear on the plastic bulb base,"

and then:

"The extra-wide plastic top ear is easily trimmed or filed to make the bulb
fit your headlamp's bulb receptacle."

My "plan" is to take one of the low beams out and compare it to the new HIR2. Then trim whatever is different. It will be simple enough with them side by side.

Maybe I'll take some before and after pics and post them for posterity.

Yeah, it's pretty obvious when you compare the two to see what needs trimmed, and pretty simple at that.

Just be carefull with the glass bulb, and avoid getting any fingerprints on it.
