Headlamps from P15D-25 incandescent to HALOGENS.

[bmaverick]

My goal was to keep the OE look to the YM machine. I've seen the LED headlamps and it took away the natural era look. Yet, finding the P15D-25 bulbs at a good price is a pain. And typically what you do find is the 25W/25W vs the OE 25W/35W (low/high beam).

After consulting a few vehicle bulb catalogs of the 70s and 80s, the H6M halogens met the dimensionals for the YM and other Yanmar models with the same bulb for the P15D-25.

Let's first look at the OE Stanley 001-1259 glass assembly.

Not too shabby for a 45+ year old headlamp.

With the P15D-25 bulb taken out, the socket is a strange one.

With my handy-dandy digital calipers, I took to the task of getting sizes.

A replacement bulb can not be anywhere touching the inside glass from the socket flange. I measured 61.2mm after 3X testing the distance. I would safely say a 52mm (2-inches) maximum bulb from the base flange ring to the top of the bulb glass is ideal.

Looking for the H6M, I came across the Wagner HM202 halogens for $1.83 each on Rockauto.com So, I ordered a box.

The H6M (HM202) halogens are plug-n-play. No mods to anything. Perfect fit. AND it's low and high beam too!

The Yanmar headlamp assembly is 194145-53200 (Stanley 001-1259). For those with a Deere 50 Series, p/n HL5414.

For many of the YM series, the following is very typical.

As you an see, the headlamps at 25W is dismal. Thus, the halogen 35W are so much better.

All of the YM Series is either equipped with a rear work light or there are holes in the rear fender for it. Mine just had the holes after the UTDA refurb.

In the YM series, the schematics for the rear worklight is simple.

Most are a yellow wire, some are green. Depends on the model. The little flipper in the schematic is the on/off switch.

I wanted a rear worklight for snowplowing this winter. And I push snow with a 6ft rear blade backwards. Yet, with no light, it's awkward at best. How to have the OE look and not a rusty 40+ year old work light is to pick up a Harbor Freight worklight.

The sun was going down. It was prime to take this shot.

For the majority of the YM series, there are two layouts for the fuse box.

A few people on the Yanmar listserv wanted to see how far these halogens shine at night.

My drive is 550FT long. Then at the end of the drive to hwy is another farm house setting back 300FT. With the high beams, about 90% of the 550FT is fully illuminated and reflections off the other farm house is noticed.

The low beams place a nice spot on the ground and a little illumination of the farm house out front.

Turning the YM2610 around and placing it right at the same fence post, the Harbor Freight worklight is now illuminated. This is a single light.

And at 400FT down the driveway, it sure is bright like a train in a tunnel coming at me.

This year, I'll be ready for night time snow plowing rather than using a flashlight in hand and fumbling around.

Cost for all the upgrades $13.16. 2-bulbs and 1 rear worklight.

But NO on/off switch for the rear light?

Yes, I added one.

And mounted it here by the fusebox. The bracket has room for 3 more switches. Thus, an LED lightbar on the ROPS could be added.

Now that's a Great headlight!!

Do they make these bulbs for an FX235 ?

Pull the bulb, take a pix and post it here. If there are numbers on it post it here too.
