## Overview

HELLA H4 100/80WTB bulbs deliver high wattage 12V illumination designed for off-road and professional use, offering superior brightness, longer lifespan, and trusted OE-quality fit. Engineered with advanced luminous efficiency, these bulbs provide eco-friendly, reliable lighting solutions for demanding environments such as agriculture, forestry, and racing, ensuring enhanced visibility and safety in challenging conditions.

## Description

When it comes to driving safety, sight is the most important sense. Visibility can be impaired under various circumstances and driving under these adverse conditions will increase the risk of an accident. To meet these challenges, HELLA is continually improving existing lighting systems and developing new lighting equipment and components. HELLA bulbs undergo strenuous quality tests. This is achieved by using the most modern equipment in light metering, which provides information if a bulb has the necessary properties.

Review: All lights should be this good. - Not street legal. BUT properly aimed the they have never caused any oncoming traffic to ever flash their lights. They were installed with relays added with 12 ga battery feed and the lighting is truly amazing, especially high beam. To me these perform better than led because they focus properly. Do your homework before going with expensive leds. I’m in rural Hawaii, country road lighting is pretty much non existent so these are truly a necessary improvement. Some reviews say they don’t last as long as lower wattage bulbs, in most cars they are a quick install. I carry 2 spares as the price is very reasonable. Well done.
Review: Huge improvement over stock. Night driving is finally comfortable - These HELLA H4 100/80W bulbs are AMAZING! I have a 1988 Jeep Comanche with the old enclosed-style headlights, and the factory lighting was way too dim to feel safe driving at night. After some research, I picked up these bulbs along with Hella headlight housings and a wiring harness from K Suspension. Holy cow what a difference! The brightness and clarity are on a completely different level. My old Jeep now has headlights that outperform most modern vehicles I see on the road. Night driving feels comfortable, clear, and far safer than before. It did require a bit of work to install everything, especially converting from the sealed beams, but it was absolutely worth the effort. The upgrade honestly transformed the truck. If you have an older vehicle with dim headlights and you’re doing an H4 conversion, I highly recommend these bulbs. They completely changed the way my Comanche drives at night.

## Questions & Answers

**Q: Has anyone tried this bulb on an BMW G650GS?  I am a bit concerned it might fry the wires, reflector or lens.**
A: You MUST use 12g stranded wire with quality insulation to each h4 socket terminal.  You MUST use Ceramic High Heat HD socket.  You Must usea relay that is 20% Higher rated than the max amp draw.  Your altenator or generator must have the added capacity so to cover the increased draw@ idle of these lamps or they will draw down the battery.  If smaller wire or alt capacity there will be voltage drop which increases amp and thus heat.  For 1 light on a bike figure for 13.5v to be safe which adds to 9.6 amps.  Use a 15 amp relay.  For high low you need 2 relays use two 15a or 1 15a hi and 1 10a lo.  If its 2 for a dual lamp or 4wheel vehicle double Watt   so 260w÷13.5=17a.  Best use 25 or 30a relay for high and low.  Ideally use a dual output relay so 1 12g lead to each bulb from  relay term not daisy chained.  Ideally run 10g from battery or alt post to relay input.  Built like this you will never have a capacity or heat issue when in good condition.

YOU CAN NOT USE ANY STOCK WIRING HARNESS!!  NOT EVEN MOST PREBUILT HD WIRING HARNESS.

If you follow the above general guide with properly crimped connectors it will not only not burn up but 2
Will have much higher light output.  Remember a 5% drop in voltage = a 15% drop in light output 1:3 ratio. Ideal voltage is 14.5V on 12v systems.

**Q: I have an original stock headlight.  Anything special i need to do to use this bulb?**
A: The current draw with this bulb is more than stock so after having the lights on for say a 30 minute drive in warm weather see if the connector at the bulb is hot as well as the wires going to it with the lights still on if so you should install a hevi-duty  connector and wire kit. My jeep 2005 wrangler handled these bulbs just fine and I think most vehicles will need nothing.....DBW

**Q: I have a 1998 Kawasaki Vulcan 800 Classic. Any need to upgrade anything electrical or does this simply replace the stock bulb? Thanks**
A: Oh yeah. You should not just plug this in and go. These bulbs make a ton more heat than a stock 55/60 bulb. Buy a ceramic plug as well, otherwise the stock pug will just melt over time. I think I paid maybe 12 bucks for 2 ceramic H4 plugs on Amazon.

**Q: Will these work on my motorcycle? it's a 2004 bmw r1150r, and h4 is stamped on the glass plate of the light housing**
A: The h4 bulb will fit, May want to check the wattage they get kind of hot. There is a lower watt bulb too I believe.

### ⭐⭐⭐⭐⭐ Didnt know they made this. Great for poor factory halogen projectors.
*by A***R on December 31, 2025*

Instant improvement noticeable over silverstars. My 2025 kia soul came with horrible factory halogens + terrible lighting design in general. They were promptly swapped to H4 sylvania silverstars. There was still something missing and then i noticed Hella made a still higher watt bulb. They are much brighter than your usual 55/60 watts, but still feel easier on the eyes of oncoming traffic. I think this is ethical. I bought an led kit as well but sidelined it. If excess power consumption, heat, or small wear life becomes an issue, i will try something else but this appears to be a winner.
