Old bulb and new headlight assembly

Post by steven0356 » Mon Jan 22, 2007 8:33 am

Ok I just bought the bulb on the left (which has very similar specifications as the original bulb in my CA77 305 dream.
I am going to try and install it into the headlight assembly on the right. All I need is to find a connector that will fit this bulb. I figured I might be able to scavenge one from a donor source or I might be able to find one new. I was able to find a generic connector for a H4 bulb I will install instead if I can't get this to work, so I know you can buy generic connectors for many types of bulbs.

So, if you can think of a donor source connector for this bulb or know the name of the connector type please let be know.

Thanks for you help

The only thing I can tell you is that Honda used this bulb on the old ATC185/200 series 3 wheelers. You can still get a socket with wires on it from Honda, part #33120-292-673 m.s.r.p. $34.84, but it was made to sit in a special shaped hole cut into the reflector. You would have to somehow mold your own socket in the back of this headlight for it to lock in to. Unless, of course, you just want to slop alot of silicone in to hold it. Kind of a sloppy way to do it, and you'd have to redo it if(when) the bulb burns out.
Tell you what, measure the inside dia. of the hole, and tell me if it has any slots or locking grooves or if it is just a plain, round, featureless recess. I will use my resources to find you as close to a turnkey solution as can be had to fill the gap between your bike and that headlight without using duct tape, coat hangers and chewing gum.

bulb hook-up

Post by fastjoe » Mon Jan 22, 2007 8:10 pm

I have successfully installed that type of bulb by soldering wires directly to the bulb terminals. Solder a ground wire onto one of the tabs. Set the bulb into the reflector with some RTV. Make sure it's oriented correctly so the high beam will be up. Put a glob of RTV over the terminal connections. Hope this helps.

I just got one of those same bulbs from Ebay on Friday.I did not like the fact that my H4 bulb drained my battery.I was hoping the flange part of the bulb ws as wide as the H4 so it could sit on the hole of the Headlight but as you saw it is too smalll.So what I did was destroy my H4 bulb($8 down the drain) to sit this new bulb into.I did solder the high and low beam wires to the contacts on the back of the bulb(I hope I got the wires on the right spot).The ground wire was the next challenge.I actually soldered it to the rim on the bulb where you can see a solder joint and drilled a hole thru my old H4 base to runthe wire thru.I think I have the bulb in the right way, but will find out when installe in bike.This may not be the prettiest job, but it will work.I use the high temp RTV to hold it in place.You could probably make up something such as I did to hold the bulb.I had looked at connectors today before doing this, but nothing seemed quite right and I believe a bulky socket would hit the speedo.Hope this helps.Here is a picture.Joe
