View Full Version : Sealed beam < H4 conversion *cheap*

Just picked up a couple of lights on friday on a hunch. Chucked one in today to test fit before I made this thread. It's a cheap H4 high/low 5 3/4" conversion to get rid of the silly sealed beams that should have died in the '60's. Anyways, The light looks great in the garage, with output comparable to the Hella on the passenger side. I didn't take the car out to compare beam patterns though.

The all glass/metal housing even comes with a city light, which involves too much work for me to attempt until the spring.

The back looks like your standard Bosch/Hella/Cebie/Autopal headlight conversion housing. Standard H4 bulb, which of course is the same plug that you plug your sealed beams in with.

Front of the lense is convexed, not flat, so it pretty much still looks like a sealed beam.

The funny thing is, they come like this:

In a box like this:

There is of course a small catch. Most H4/H1/H3 sealed beam conversions have 3 small tabs on the back of the housing to mock the 3 tabs on the back of the sealed beam (around the very outer edge). This is of course to make sure that the housing/beam is installed straight up and down, as seen below: (pictured is a Hella H1 5.75" highbeam)

The Hilux unit only comes with one of these tabs, so once you have the housing installed, it will rattle ever so slightly. When you actually install the unit, that single tab is at the bottom, so all you need to do is wedge something at the top of the lense to act as a spacer and you're set. I figure something like a piece of 8 gauge wire will be enough to fill the gap enough to properly secure the light. Not a big deal at all!

So there you have it! I'll be using these through the winter to save my Hella's from the elements. Who the hell wants to change an entire sealed beam in the winter when you can just reach behind and change a bulb?*th-up* If you want to try it out for yourself, just head over to Princess Auto, of course! :rolleyes::

Why not try it? It's easier to find at the moment than Hella/Bosch H4 conversions. If you're still running sealed beams, I don't see why you wouldn't try these out. Wait, speaking of running, do you have anything that stays running long enough to keep the lights useful, John?

Lmao great find!

They are street legal as far as I can tell, but if you've ever bought Hella or Bosch conversions, they always say "For off-road use only".

errr? I did say I would try this. Anyways, no the car doesn't stay running long enough, but hopefully I've been advised of a fix that I'm trying........fingers crossed. 1 day with no stalls!

It's off road because it's a 100w bulb?

It's not really off road. It's a snowplow light for pickups, so it is street legal. I was just joking because thats what all the Bosch and Hella sealed beam conversions say on the box.

It's a standard 55/60 dual filiment, low/high H4 bulb. Usually when they say "off road use only" it's not becuase of the wattage, but more for the beam pattern, but again, I was just kidding.

Now I don't feel so bad as I installed two additional sets of driving/spot lights on my truck. Gotta see the road when booting out to London in the dark. Princess Auto is a great place for these lamps. When it goes bad or rusts its pretty cheap to replace or upgrade especially when they have their weekly sales on these things.

Hows the beam pattern? If I had an E30 with base lights, I'd definitely do this upgrade in a heartbeat. Good job Scott!

Hold the phone on this for the moment. I just chucked both of these onto the car last night. I'm sort of underwhelmed.

The beam pattern; Not as direct as I would have liked. Seems to be more of a flood than a spot. Not like your typical Euro ____/___/ pattern.

Brightness; wasn't great, but I have no sealed beam to compare it to. Compared to the H1 Hella's I'm running, these are ****ing shit, but then again, the H1 Hella's are a 60W highbeam that I've aimed low, and I'm running 100W highbeams, so my idea of a good light has been askewed by having wicked lighting. The bulb is made by some company that i've never heard of, so maybe a proper manufacturer like Osram or Hella could have made these a little brighter.

Speaking of bulbs; One of them exploded inside the housing and all I did was drive it on some backroads for 10 minutes, switching from Highs to Lows. WTF!? Anyways, it smoked the inside of the lense (and not in the cool way), so I've gotta return one of them.... or maybe both. *mumble* Drove to work this morning with no grills and three lights on the car. Reminded me of MaxBell's car.*th-up*

But it has a city light!!!!!fcplm

I think if anyone wanted to use these, they might want to run a HID H4 conversion in conjunction with these lenses just to push out some more brightness.

Or, stop being a cheap ass and buy Hella / Bosch / Cebie / Autopal conversions instead. Cheap bastards!! :D

Stock wiring for 100W?

Dude valiant effort.. really. Your story reminds me of when I fabricated GSXR mirror-turnsignals onto my CBR600. In my case it worked, but you get it. :)

Yeah, been running 100w H3 highs for years, never even blew a fuse. I do lots of night driving on backroads too.

Technically this works... it's just that the bulbs that come with the lense are crap. I've done Hella, Bosch, Autopal, and they all work fine, but I'm using quality bulbs with them... when I found these, I figured they're pretty much the same thing. They're just not as bright as I'm used to, which is all that counts really.*mumble*
