What *size* is the Seca square headlight? Want a Hella.

The larger of the two headlights. I want to use an H4 friendly lens, perhaps something from Hella. We've both used Hella lenses in the past and both of us prefer the patterns they have. Holeshot has used them in everything from a 1972 Chevy LUV to his prized (and rare) 1984 Harley Davidson XLX (rip). They just seem to work well on the very dark highways we have out here. There isn't a streetlamp for hundreds of miles.







Gag! You really do not want to have to push home in this heat. Just sayin' .. we go for reliability and practicality when possible.

So anyways I want to use a specific type of H4 bulb that Holeshot taught me about, from what I understand I'll need a new "lens assembly" to do so. (Y'know, the part that looks like a "sealed beam"). So I'm trying to determine what I need to buy to make that happen. I still need to get the *bucket* part as of yet. Reason I'm going square: It matches other machines we've already started to build. We're trying to get all thematic on ya!! (oh brother).

I'm using the bigger square headlight off the Seca. It seems to measure around 6.5 x 4.5 or so .. depending on exactly ~where~ I measure it. But I'm not sure what it would be considered in actuality.

So is there a dimensional standard that these Seca headlights use? Er whutever? I'm speaking of only the square ones (ok ok .. rectangular .. alright already .... geez shut up ~mom~!). Woops .. did I just say that out loud? Haahaa!

Anyhow .. any help for a poor defenseless ~stupid girl~ ?? :wink: :wink: :lol:

Thank you!

Dear Honey Bee,

Buzzzzz, bzzz, bzzzzzzz, bzzzt, .....

Whoops, sorry 'bout that.

Hella does not offer a replacement for the stock Yamaha rectangular headlights....neither the main lights nor the smaller auxiliary lights. In fact, nowhere have we been able to fit a drop-in replacement for the stock lense/housing unit....it's a unique design (originally made by Koito) for Yamaha that no one seems to want to develop as an aftermarket piece because of the very limited applications.

De nada.

 

From My understanding. The Seca Square/Rectangular headlight uses the H6054 style bulb

This sounds like it should fit what you are looking for.

Then again. I may be wrong!

Chacal, so what is the best option for retaining the stock rectangular light but actually being able to see the road? Or should I just part with my weird lamp and look like everyone else for safety?

 

Well, the first thing to do is make sure that ALL of the connectors (including the ones inside the headlight control switch) in the headlight circuit (starting from the fusebox) are zestfully clean and free of corrosion.....corrosion drops the voltage in the circuit, and reduced voltage at the headlight results in dramatic decreases in light output (i.e. a 10% drop in voltage results in a 20% decrease in light output, etc.). And the "wattage" rating of most bulbs is actually "rated" at 12.8 VDC, and again, as volage drops off, light output drops even quicker.

Next, you could consider upgrading the bulb in your auxiliary light; stock, it's about 35W (again, all the considerations as above apply) and go to a 55W bulb. That might help some.

Other than that, I have no solutions. But I bet if you are diligent in simply cleaning all the connectors between the battery and the headlight, you'll get a much "brighter" picture of what you might need to do (if anything).

 

I always found it so weird when ppl say they don't get enough light with the rect. headlight. I may be going on a bit of a rant here but i can see perfectly fine with mine, even on low beams.

It just seems like if you don't have little suns for headlights these days, ppl don't like it. (referring more to the new model cars with their blinding low beams, and hibeams as daytime runners (Jeep, Seabrings, some PT cruisers)

I may find myself this year, leaving my hi beams on all the time on the bike, day or night, because every car i pass looks like they're doing the same lol.

 

Given the condition of the rest of my bike I'd bet the connectors are not pristine . . . I'll give it a go. Didn't realize it made that huge of an impact.
