Yes, H7 55W halogen - when I have a choice I usually order Osram Night Racer.

Fit a new pair while you are at it & keep the good bulb as a spare.

Alternatively use search to explore alternative options. Many chose to fit LEDs, if are legal in your jurisdiction.

Yes H7 halogen is the correct bulb, higher output versions are available but they also have shorter life, my 2013 Tenere never had a headlight bulb last 10,000 miles, my 2018 the first bulb burned out at 24,000 miles, the other bulb was still working fine at 29,000 but I removed them both to replace them with Cyclops LED’s .
Also tried a set of the Novasight LED’s they looked very bright but riding after dark they were even worse than the stock H7 Halogen bulbs.

In recognized brands, there are H7 lamps with 70/80 and also with 100w (each one). "Perhaps" the problem would be the consumption specification (100w) for the S10 electric instalation, and above all the lamp durability. In My particular case, the H7 bulbs they thast longer (in miles), when they are in constant moving (road,highway, etc). The h7 bulbs tend to last much fewer miles, when this miles are made in the city/town…..It only occurred to me that "perhaps", the temperature of the headlight on the road is lower than in the city due to the action of the air, and also helps to dissipate the temperature of the bulb

But the rule of the halogen bulb, that if you put 2 bulbs together, when one burns out, the other burns out after a few days/miles... it holds for both the road and the city:):)

The more I read, and the longer my OE bulbs lasts, the more I'm convinced that the metal flap that covers the top of the "high" beam is reflecting heat back on the bulb when on "low", causing a failure. I ride on "high" all of the time during the day. I rarely ride at night anymore. Jlq even notes that they don't last as long in town. Due likely to riding on "low" beam more than out on the highway.

“Specifically” I was referring to the duration of the H7 lamp, compared to another lamp that is normally used in headlights (H4, 9003, 9005, HB3, etc, etc…), but in my reference, the example of use I wasn't just focused on the S10. In my personal experience, in the use of various and different types of vehicles in night driving (dawn and dusk) during every week of the last 25 years, the H7 lamp was the one that "always lasted less". I tried different brands and it was the same. The worst ones are the ones that offer the most brightness, and the blue ones (where blue is a coat), start well… after a short time they start to change color, and if you take out the lamp you will see that the coat is starting to burn on the part top of the bulb by the action of the heat of the filament. Until a while ago, I maintained that the H4 lamp was like the best I had ever tried. But over the years, technology has changed. Today the vehicle I drive is equipped with adaptive LEDs, and the truth is that the light beam is practically perfect. But that beam of light is related to the headlight. I have driven "other vehicles" also with adaptive LEDs and the beam of light was terrible, incorrigible. Normally my night trip (outward or return), is usually accompanied by cows, horses, wild boars, which usually cross or graze on the side of the road, that's why I "need" that the lighting is excellent.
When comparing the H7 between city and highway, I did it by comparing the use that I give it (highway), with the one that other members of my family or friends give to the same H7 (city)… in the city, they last much less weather…..
Same today, I still maintain that "The system" of the H4 lamp is better than any adaptive led of today, for night driving, at moderate / high speed, The H4 lamp "turns off" the low beam and turns on the high beam. On the other hand, in the adaptive LEDs (or headlights with double headlight/lamp), the low beam "does not turn off". That is, when you switch from low beam to high beam, the high beam is added to the low beam. As the low light beam remains "illuminating so close, too", this causes an excessive unnecessary reflection on the useless in front of you (reflection on the asphalt or on the reflective marking lines), which causes extreme eye fatigue (especially central discontinuous demarcation lines).

I agree with your liking of the H4. I have a 55/100w in my FJ. Been in there for years/miles. It's single beam 100w high beam provides more light than many car dual headlights. I always assumed that when headlamp lenses went to being plastic, they did away with the H4 due to the excessive halogen heat. My FJ has an "old fashioned" glass lens and heat isn't a factor. I have seen plastic lenses that have large "bubbles" in them from bulb heat. I still maintain that the more "low beam" riding a person does on their Tenere, the shorter lifespan of their "regular" bulbs will have.

My Osram off-road lights have been on low pretty much their whole five year life so far. If one should fail I'll be replacing them both with the same.

Wondering about H7 seating in the S10 bulb holder. The Pic is not great, but I think you can see that the width of the bulb tab is wider than the socket in which it sits. As a result, it doesn't sit flush on the surface of the bulb holder. This is a Sylvania bulb.

Is this normal? Should I trim the tab? Do I have the bulb oriented correctly (tab up)?

Thanks.20220909_182902.jpg

Yamahas poor design makes it difficult to tell where the tab is supposed to go, it belongs in the 7 o’clock position.

On a Honda Goldwing it’s very easy to tell the tab belongs in the 12 o’clock position, it won’t fit in any other position.

Thank you for that info. The socket shape is misleading. I'll make the appropriate adjustments.
