Outer Limits 4x4 Board

What is the difference between an IPF 812H rectangular conversion headlight and an 821H headlight? On the following site http://www.ipf.co.jp/English/products/OTHER/OTHER.html it refers to both of them as 4 light systems and lists what looks to be bulb wattages.

What does the 4 light system mean and do these take replacement H4 bulbs?

I can get the 820H lights easily out of the U.S but the 812H and H21H lights are a lot rarer to find online it seems and I'd prefer to get them since they illuminate the left of the road more and we drive on the left in my part of the world.

I tried doing a search before posting but the search function doesnt seem to be working.

I'm gonna have a guess and go with that the lens is designed for use with a H4 bulb with two wire elements (halogen bulb) - hi-beam and lo-beam. So having two of these lights could be considered a 4 light system.
Only a few spot lights are like this, having both lo and hi beam functionality.

A 2 light system would be two lights with their lenses designed for a single point of light source, ie a H4 bulb with only a single wire element. If this is the case, majority of spot lights would prolly be considered a 2 light system, majority of them using either a single H1 or H3 bulb - there are a fee exceptions to this.

But don't take my word for it. I'm only guessing here. Just tried doing a few googles to find the correct info, but didn't get very far.

I read it a little differently - and aren't they headlights, not 'driving' lights. As in they are designed for 4 light system where you have 2 seperate lights for hi and low beam (4 in total)

e.g. the H12 is a low angled lens, and the H21 is a high angled lens.

If you are using them jsut as replacement headlights, i'd say check out the Narva range. I got the 7" halogen replacement for my 79 MGB and they're great. Hopefully they;re rectangular version is of the same standard. Only about $120 for the pair too.

Yeah, I think 4 light system means like an 80 series cruisers setup (with 4 globes).
On low beam the 812H will be illuminated (Low beam filament). (80w) per side
When High beam is swicthed on, the 812H high beam filament turns on, so does the 821H globe. (110w +110w) per side

Whereas a 2 light setup uses 2 lamps, each with a globe capable of high and low beam, such as the 860H. The pattern of light would be slightly different between the 2 and 4 light systems.

Thanks for the replies guys. Yes it does seem it is a separate headlight for high and low beams as opposed to the 2 light system with an H4 bulb that does both. Also the 812H and 821H are physically smaller than the 820H.

It seems the IPF 860H headlight conversion is the one I'm after because it's fluted to give a brighter beam on the left but I'm not having much luck finding an online retailer of them in the Western hemisphere. I might end up havin to get the 820H and hope the police over here don't object too much to em

Just get the 820H and swap the left and right lamps

As long as you aim them correctly, I cant see a problem.

Not sure if you're joking, but you won't be able to swap them over side to side. As each individual lens is focused to the correct side of the road.

I'd seriously look at the Narava offerings. They are pretty damn good. What kinda car is it goign in? (Also the narva's have the option of being sold with a 55/100w globe, so the highbeams would pack a real punch).

I did that exact upgrade with the IPF Xenon 55W/65W FatBoy globes in all four lights. All i can say is they are 10 times brighter then what my standard ones were when it comes to both low and high beam!!!

They're going in a 2003 Hilux. My choices are really Hella or IPF due to ease of availability from US suppliers. Unfortunately both are going to be fluted to increase light on the right hand side of the road instead of the left where I need it. I guess I can just try aiming them more to the left instead of straight ahead like stock.

I was going to put Fatboy bulbs in either the Hella or IPF lights. From what I've been reading on Outerlimits it seems the IPF lights have a thicker/stronger lens on em. I currently have 90/100W cheap H4 bulbs in a cheap No-name H4 conversion setup that uses chromed plastic for a reflector which is a bit brighter than stock but is still crap.

Just put the ipf 190w low 150w high in my patrol and they are substaintially better than the old sealed beams. Only draw 60/55w as well apparently although i don't know how that works

Dont fit IPF fatboy globes. I have found these to be very disappointing considering the price. The 80/110 globes were much better.
