Headlight integration for a 2021 RAIL 9.7

[Third-Reef]

HAs anyone installed a good light that is bowered off the Bosch system? Looking to do this to expand my biking hours.

Any reason why you wouldn't just get a decent self contained one? Battery anxiety in the day is one thing, but when you risk being out of assistance AND light, bit more of an issue! Always liked Exposure myself. Amount of lumens required depends on what you want to do really. Going fast on tech stuff = more the better really, and a helmet/bars combo. On tracks you know well with low risk, anywhere between 700 and 1500 is OK IME.

I have. It is neat to use the same battery. Heard there is a special reserve for lights. Trek included the wire already (you need to fish it out though) but you need to stop by LBS to activate it. Now I can switch on the lights from the Kiox by pressing a button.

I like the Lezyne 1000 ebike light, it's compact and its current draw in within the Bosch system specs.
I still add another separate bar mounted light and a helmet mounted one as well. (The helmet mount ensures you have illumination where you're looking not just where the bars are facing). YMMV

Exposures are good, had Sixpack once. I'm still waiting my Rail 7 but i have Lupine SL SF allready waiting. SL SF because i do lot of commute also. I'm planning to buy Exposure Diablo to helmet with Lupine. That's enough for my needs.

EDIT: I have used my Lupine allready last winter with my current bike. It's fairly good. Beam has very sharp edge but with high beam it's okay in the woods if trails are fairly flat. Lots of ups and downs and the beam is too limited.

yeah bosch bikes have a reserve programmed so if your assist goes out you still have lights. but i think your dealer can adjust the amount of reserve????

 

[Mr_Price]

I asked my LBS about it and they suggested avoiding it, as above to conserve juice, but also they have seen 2 bikes come back with messed up electrical problems.

 

[protowheeler]

Hate to say it, but that's pretty lame advice. Yes it does conserve battery power but at the lowest reserve setting I only saved a few KM. And if it's a good light and connected properly, issues shouldn't occur.

Is this the same LBS who said there was no chainring clearance because of thick paint on the frame?

Change your LBS

Haha to be fair, that clown has backtracked massively and is sorting me out. LOL I should update that thread.

It was his head tech that was telling me to avoid it.

 

[Man of Finland]

You should avoid your LBS instead. I have the Lezyne 1000 and its working perfectly!

How was the integration with the Kiox.

I have the Lupine SL X wired into my 9.8 and it is great. I also recommend the Lupine tail light that is integrated into the seat clamp, as well. We do a lot of night rides, so its just slap a light on the helmet and go.

I don't need a hardwired light. I run a Niterider 4200 Enduro on the Bars and a Light & Motion SECA 2500 on my Helmet.....All I need to light up the night sky all night.

The Lupone SL X apparently draws 30 W at 2200 lumens for high beam in the default settings, but only 18W at 1600 lumens for high beam in the eco mode. Given the Rail Bosch light power is max 18W, does the light work on high beam in default mode, or do you have to run in eco mode, effectively making this light 1,600 lumens max on a Rail?

 

[GolfMaster52]

I honestly do not know what the output is. But, I never ride in eco mode. On a normal EMTB mode ride, you can have the outer lights on, like daytime running lights on a car. When it transitions to dark, the main light in the middle automatically comes on. Then, anytime you want you can toggle it to bright and it is significantly brighter. Not sure if that helps, but hope so.

I have installed a magicshine MJ 902s and it's working perfectly ?MJ 902S

I can post some pictures later

Last week I installed a Lezyne Macro Drive 1000 in front, a PDW Kepler on the rear. About $120 total. With the Rail wired for the front already, I just had to fish out the wire from the top of the downtube. Rear required taking the cover off of the motor. The Kepler included the Bosch connector, though the wire was way too long so I cut it to size. Brought it to Trek to enable/set wattage.
