Hella H4 12V 100/80W Halogen High Wattage Bulb Off Road Use

Hella H4 12V 100/80W Halogen High Wattage Bulb Off Road Use

Q: Has anyone tried this bulb on an BMW G650GS? I am a bit concerned it might fry the wires, reflector or lens.

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?

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

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

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.

Great option for the Jeep TJ with Hella housing

Works great with the Hella 7” housing for the Jeep Wrangler TJ. Plug and play, significantly brighter than I expected without shelling out for LED Headlights

They worked fine in my FJ Cruiser for about 6 months then low beam of one bulb got fused. Replacing the pair with Philips now. Let’s see how that works out

Excelente iluminacion

Si tus faros estan en buen estado, tendras una muy buena iluminacion con estos focos, el unico detalle, tienen alto consumo de bateria, pero es un buen producto

Very yellow!

If you want the yellow headlight look without using tint, these are amazing. They’re a very deep yellow, but they’re also nice and bright.
