Got a Prius for free, looking for some advice. Have some DrPrius info.

Aux beam S series in you're proper number like 9003 . I have very bright. You must crank your adjusters down about eight half turns while you're doing this you'll see the cutoff line all of a sudden just magically appear on the garage door then you need to set that line at the proper height I have no idea what it is nor care It's country dependent probably and then go do the other side you'll be amazed at how bright the light and the cutoff is quite good for an open lamp such as these of course cleaning and making sure there is clear as possible goes a long way even if the plastic has hairlines in it if it's relatively clear and clean makes a big difference and the aiming bringing the LEDs down will get you in proper aim pretty quickly and you'll have very bright lights and you probably never address this issue again as long as you have the car even with a cracked headlight and water getting in the LED still work and are fine they're IP rated I have them in all four generation twos and two generation 3s and they are well worth the inexpensive price paid very well worth it.

 

Tombukt2, others: Heads up. Apparently it is ILLEGAL in the United States to replace halogen bulbs with LED bulbs.
If your vehicle resides in a state with annual inspection, the modification will be flagged and the vehicle will be failed.

ANYONE actually install LED headlights in Gen1? | Page 2 | PriusChat

 

Seems SAE has been working on a standard J3145 that would allow for acceptable LED retrofits, but I'm not sure what the hold-up is. This report from 2018 looked like things were already pretty well along....

Once SAE releases a J3145 standard, I guess the US Federal Motor Vehicle Safety Standards would then have to be updated to allow products that comply with it. I guess that's usually gone through NHTSA's rulemaking process, but maybe with Chevron deference no longer, somebody could object and it might never happen without an act of Congress.

 

Not in North Carolina I have annual safety inspection no emissions I can have blue lights on the car and all kinds of nonsense which in most townships states they're illegal. Inspection doesn't flag them they generally looking for window tint that's a big thing here flagging dark window tint because it makes your car comfortable and stuff you know and the cops can't see through it and so that's a safety concern so on and on and on I don't know what they're going to do when the automatic blackout glass starts getting fitted to cars You just push a button in the car You can't see through it with a flashlight stuck on the glass but anyway I've had no trouble with LEDs especially once you get them aimed properly in a fake projector or an open housing like the generation 2 sticking them in there and not cranking down on the adjusters about eight half turns you've done nothing You're just blinding people literally it's horrible. And if you think the laws are bad here go to Europe and change a headlight bulb they can flag your car take it off the road and have you paying them money I think it's TUV standards here in America nobody does anything lawyers aren't even smart enough to take people to court because their brake lights didn't work I watch court cases and listen to testimony quite often it is hysterical but yes I think you're correct the law still reads that these LED headlights all of them are for off-road use only I've been using mine on road aimed properly for 7 years or so now and before that I was using HID installs in glass housings and things aimed properly never had an issue and even down here in North and South Carolina crickets

 

Toyota never fully charges or discharges the traction battery; that is how they can confidently warranty the HV battery for 10 years when new. They just cycle that 15-20% "sweet spot" in the middle range of the battery and that makes the HV battery last way way longer than the usual 1000 cycles for Lithium Ion or Nickel metal hydride batteries. So, it sounds like everything is OK with your Prius from the data you've provided.

 

What I've been seeing is the engine will start to charge it if it gets down to 40% SoC, and regen braking gets completely replaced by engine braking by 80% SoC. The car likes to keep the SoC right around 60%, the middle of that range, when it can, like on a long straightaway.

So the sweet spot it likes to stay in is more like 40% wide.

 

I'll buy that figure; mine was just a guesstimate based on my observations. Android phones even offer an option in Settings to limit charging the phone battery to 85% now (to prolong battery life by limiting cycle range).

The big problem comes when someone new to Prius mistakes the limited duty cycles (purposely engineered by Toyota) for a bad or Ill traction battery.
