Very cool, I ended up retrofitting a projector on my Prius but I just went with the cheapest LED projector on amazon. It's been working great and it cost me less than $100
Mr Blacktree... Your tutorials.. DIY and how to's have informed me to improve my Prius.. I picked up a tow hitch and 1.25" to 2" hitch adapter for $50... Going to do a diy hitch cargo box next.. I will check through your library for a video
@@michaelblacktree it would be prudent of me to let you tackle a project like that first.... This LED video will keep me from wasting $.. I want to improve the fog light output.. they are ineffective the way they are... Possibly rewiring the fog lights to work independently of the head lights???
I installed LED fog light bulbs from amazon. They were so bright, I had to add a dimmer knob. I didn't film it, but I talked about it in the EcoModder build thread. Here's a link: ecomodder.com/forum/showthread.php/prius-experiment-40050-21.html
I replaced my HIDs on my 2nd Gen to LEDs. $50 on Amazon.(Better then $200-$250/bulb HID replacement) And the install was pretty straightforward. Though, I did pull my headlight assemblies to do so. I thought having the LEDs in a HID housing was going to overkill. But I was surprised that my housing still have a very crisp cutoff that I was able to adjust accordingly even with the reflectors still installed. I have no been flashed at all since install and I do a ton of night driving(95%). So no angry motorists which is a plus to some. Also, the LEDs are so much brighter and whiting for the HIDs I replaced them with. Win/win in my book.
I retrofited proper Bixenon Projectors into the oem housing - You can´t compare the performance of really good projectors to LED bulb upgrades - projectors are so much better and dont blind at all when adjustet correctly..
@@michaelblacktree yeah they are the best and it´s not that hard of a job to do on the 2nd gen prius :) morimotos or nhk´s are great for the price, but all in all its not that cheap. My setup was around 500€
now i watched your video to the end..exactly my thoughts about the temperature - dont like the blue-ish look of leds. That´s also why i chose and bixenon projector and not an led one. 4300k osram night breaker laser d2s bubls are perfect..
Now you need to swap out your fog lights with LED lights. Elevate your Prius to the next level. Tell auxito to send you a pair and a discount code for your viewers and or a give away HID kit for Prius gen 2 and why not a regular led pair too
With all of those LEDS installed do you think you will notice any MPG improvements? I find it easier to notice marginal gains via a full tank rather than burning a quarter or half a tank at a time then topping off because that introduces variables.
@@mq1506 I’m probably being optimistic, but do you expect fuel improvement from this mod? One step further would be LED brake lights/running lights as well. I did the same wheel covers as you and am seeing a consistent 50+ miles of range with regular driving habits
I've experienced the "fuel bladder inconsistency" mentioned above. I actually stopped using fill-ups to gauge fuel efficiency mods, because it's too inconsistent. In the future, I'll be doing coast-down testing of the aero mods instead.
@@leveluplife8585if we do a bunch of handwaving math, one liter of gas will power a 55 watt halogen headlight for 159 hours if we assume 100% efficiency of converting fuel to electricity. Realistically after the power has gone from the engine to the generator and then into the traction battery and then through the DC-DC converter into the 12V battery, I'd guess only 5-10% of that petrol becomes electricity. That roughly works out to say 5 hours of halogen headlight usage from 1L of gasoline. However that assumes you're not using power from regen so it's really a worst case scenario. If we assume that switching to LEDs draws 10% of the power then you'll only use .1 liters of gasoline over a 5 hour period of headlight usage. I average about 3L of fuel for every hour of driving assuming my average speed is 50 km/h. Turning on the halogen headlights would raise that to about 3.2L per hour. That's a difference of 39 MPG to 36 MPG. I've done a lot of handwaving here but by my estimates, the switch to LED should save you 2-3 MPG in a worst case scenario.

Thank you for making this video!! I almost bought LEDs with heat sinks thinking it would fit my gen 2 Prius
Glad to help!
@@michaelblacktree what bulb do you use for your corner marker light
Stock replacement
@@michaelblacktree what bulbs do you use for your fog lights? Also I appreciate you responding :)
The fog lights use 9006 / HB4 light bulbs. I'm using LED bulbs. But the beam pattern isn't very good. So I might change them.
Mr Blacktree... Your tutorials.. DIY and how to's have informed me to improve my Prius..

Very cool. I haven't done a cargo box but I do have a trailer.

The fog lights are LED already. And the pinned comment has a discount code.
With all of those LEDS installed do you think you will notice any MPG improvements? I find it easier to notice marginal gains via a full tank rather than burning a quarter or half a tank at a time then topping off because that introduces variables.
It's difficult with the Gen2 Prius as the tank has a bladder system that doesn't always allow the same amount of fuel.

Legal to have amber color in the parking lights like you do?
Is this a joke?
@michaelblacktree you should be asking that about the jeeps with red headlights...
