Hella 002850811 Hlmp Kit 5 3/4" 135Mm H4 12V Ece

Check your wiring and do your math to ensure your system can handle the wattage - most cars need a separate harness. These are excellent with superb pattern control and the classic right-side uptick of E-code headlights (for right-hand traffic). Given that 99% of the time you're probably running low-beams only (maybe with fogs), these are a great bang-for-your-buck where E-codes are legal. I've had two sets on two different cars, and in the 7 or so years I've owned them I've been very pleased. I can't say the same for the cheap knock-offs (which I've also tried) - these are the real deal. If you're trying to save money, Hella knock-off high beams are a better idea than skipping these. I should also note that the glass seems to be of excellent quality/extremely rugged as my 7 year old pair (on a car driven over 110k miles in that time) still look new. (installed on a 1980's 5-series BMW - needed relays, but no bucket trimming)If you really want excellent forward illumination, I highly recommend investing in a decent set of fog lights too. They provide more downward/peripheral illumination to show those critters at night when you can't run your high beams. Again pattern control is key here so you don't blind oncoming traffic and you get the light where you need it. Headlight protectors of some sort are a good idea for fog lights and if your headlights are placed where they'd be prone to damage. Glass and metal construction always winds for longevity too. Just realize fog lights are NOT the same pattern as "driving lights" - Driving lights are a high-beam style patter and WILL blind everyone else on the road.Stock bulbs this ships with are fine, if you want maximum output, avoid coated bulbs as most work by filtration. Alignment WILL be necessary after installation too, but it is very easy to do on most cars. I've never needed/felt it necessary to run high-wattage (and illegal everywhere) bulbs in mine. Just be sure your wiring harness is in good shape - you don't have a bad voltage drop with the lights installed/on - and any decent 9003/H4 will work fine.

Update:This is my first experience with e-code lamps. It’s very different from a traditional US sealed beam. There’s a tightly focused hotspot for distance vision immediately below a crisp cutoff, with a raised triangle above the cutoff to the right. It’s not a tepid amount of light either. If I could bring these back into automotive style I would. Halogen goodness with clear optics, a far better reflector than the accuracy of so many plastic oem offerings, and the low-glare clear illumination that halogen brings.I mounted these in motorcycle bucket housings and then set them up as auxiliary low beams. A proper connector socket extended too deeply so a hole had to be made to clearance them in the back (not visible). If one wanted to avoid the hole, 90 degree spade plugs and maybe bending the bulb contacts might suffice, and you’d want to source high-temp wire for the connections close to the very hot bulb.Quite pleased. Fun project.Original:right up front, I have not installed these yet. I want supplemental low beams, something you can't get any more, and figure that these in a motorcycle lamp housing will be far better than any "fog light," driving light or the other LED offerings today which have poor optics and beam control.So far, so good. The housings and lens are full glass, front and back. The reflector service is about the smoothest mirror surface I've seen with minimal ripple or waviness to include even plastic OEM headlights.Hella is a weird company. I've had plenty of their fog/driving light products. Their simple products seem the best - the *basic* fog lamps, these basic beam replacements - seem top notch, and on the other end they have all the modern shaped lights which provide results from mediocre to awful. If these work, will buy more.

I installed these in my '67 Firebird and love them. They have a crisp horizontal cutoff on low beam so you don't blind oncoming traffic and light up the side of the road so you can see any hazards to the side.High beams light up EVERYTHING!The only downside is that I had to cut out some of the center part of the bucket so that the larger light base and retainer would fit, but it's not too hard of a job with a jig saw or cutoff wheel.I ditched the incandescent bulbs and installed a set of Beamtech H4 LED bulbs that are 6400K and a much whiter light.https://www.amazon.com/gp/product/B073ZD9ZPX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

The media could not be loaded. 1971 Buick Riviera.I didn't like driving the car at night with the standard Wagner sealed beam halogen lamps I bought when I restored the car. I replaced them with these Hella products:Hella 002425811 Hlmp Kit 5 3/4" 135Mm H1 12V EceHella 002850811 Hlmp Kit 5 3/4" 135Mm H4 12V EceWhat a difference! Yes, the front face of the lamps is flatter than original, but no one has noticed. They have noticed the wire harness and relays I installed to switch the power, but I wanted the option to upgrade to 100W bulbs in the future. In the attached video, these are the standard H1 and H4 bulbs.The reflector assemblies fit in the bucket with the factory retaining rings, however, I wasn't able to use the dust boots and will have to take out the headlamp buckets and do a little opening so the dust boots will fit.I'm eyeing up an old C2 Vette to tour the nation with and I will definitely order these again so I can see at night.

They are definitely brighter than the old headlamps but you have to do some modification work for them to fit squarely in the buckets and the beam pattern is not so great. They are a so-so improvement.
