Single headlight + Hi & Low

Hello all!

I would like to mod my 2007 CBR600RR (currently with a single headlight (Low).

I've been trying all day to figure out a way to do it with no luck.
I was thinking of trying to make a H7 fit and wire in the high beams from the other loom?

I have searched high and low on multiple forums and it seems like no one has done this?
Reasoning: I bought the bike with this fairing kit and need to have both high and low beams in order for me to roadworthy the vehicle.

I need to do my roadworthy in 14 days, so its crunch time!
Any help at all is highly appreciated.

I’ve done this with a set of LED lights. I bought some H4 led bulbs. This brand bulb comes with dual high low beam on the bulb. Many of these led bulbs have removable bases so I got a H7 headlight bulb base adapter and swapped the bulb to the new adapter. H4 bulb have a 3 pin adapter as opposed to a two pin because each has a positive for the high, a positive for the low, and a negative (ground). To wire them in, you run an extra wire from each side under the ram air and tap into the high beam (+) on one side and the low (+) on the other. You then wire this to the appropriate terminal on the light. Now you have dial high/low on both sides.

Easier than this tough is to just buy the kit from Tripage. He makes the best lighting solutions for these bikes and his system is plug and play at a good price.

here's the deal.

an h4 light bulb is not designed to have both filaments lit at once. so you can't just run your high beam wire over and connect it to the second filament on the h4. you'll drastically reduce the lifespan of the bulb and may even melt your headlight housing.


in order to do this properly, you need to install a relay between the wiring and the bulb. put your low beam power on the common terminal, put the low beam filament on the normally closed, put the high beam filament on the normally open, then wire the positive to the high beam from the bike to the coil, then ground the other side of the coil.

this will have the low beam operating normally, and the high beam switch on your bike will energize the relay, turn off the low beam filament and turn on the high beam element.


this is really the only proper way to do it.





the only thing you'll have wrong with your bike at that point is you'll have an inappropriate reflector for either the low or the high depending which side you use. so it's not a perfect solution by any means. you'll either have a low beam in high beam housing (you'll annoy drivers and have poor light in front of you), or you'll have a high beam in a low beam housing (poor high beam performance at night)

Thanks all for the input.

This mod is simply to pass the roadworthy here in South Africa.
I managed to cut a H4 to fit the H7 socket on the standard light.
I got a LED H4 so im not to stressed about the heat.

The pattern is all messed up so ill be putting the proper one in as soon as the bike passes inspection.
I accomplished it by wiring the positive and negative OEM wires to the corresponding pins on the light, then taking the high beam power and plugging that into the highbeam probe of the bulb.

Simple and did it without cutting anything so it will be easily removed when im done with this.

Thanks again!
