'10 Prius headlights by whitey9

Yes you probably can with replacement "brighter" headlight bulbs like the "Silverstones". But you may face the same situation I did w/my Prius.
Due to the increased current draw of the "Silverstones", the plastic connector, and some of the adjacent wiring melted. The light would not light, and due to the damage, I could not "unplug" it from the connector. I was, however, able to obtain a like connector and wiring pieces to save me from having to replace the complete headlight ass'y. These were NOT available from VW, but since I worked at Mercedes-Benz, I was able to find the "repair kit".
My advice is to stick with what the Lord gave you. Or possibly face costly replacement(s).

To tell you the truth, the "Silverstones" didn't really perform a whole lot different/better than the "projection" headlights with the original factory halogen bulbs.
I received a rebate when I bought the "Silverstones" and they cost maybe $10ea.
But the "repair kits" and my labor made them no bargain.

Sudden loss of power doing 65 MPH by wingman

Returing home from Atlantic City there was a click and then no power. Engine just quit.
 
2007 Prius with less than 7500 miles. No nav.
 
Was doing 65 mph and in the passing lane with a bus on my tail. Finally got off road without getting killed. Put vehicle into park and turned off everything. Did a restart and had no more problems for the remaing 70 miles.
 
Really scarry.
 
Anyone else lose power?

2009 Prius 15000 miles No Nav
 
My wifes prius has experienced this exact issue on two ocassions.
 
The first time Toyota took the car and 3 days later with the help of HQ stated that there was a loose communications wire that connects the battery monitor system with the control computer.
 
The second time they took the vehicle and it is still in the shop.
 
This is a large disappointment as this is my second Prius and also own a Toyota Camary that has had a steller performance record.
 
However, this is a huge safety concern when you suddenly loose all power and then you have to jump to the shoulder and put on your emergency blinkers becuase it just wont go over 10mph.
 
She called the dealer and told her to drive to the dealer that it would do no further damage to the vehicle to drive it to them HEY offer to tow the vehicle because you are placing your customer of 3 hybrids life at risk !!

They most certainly DO illuminate. I have a 2004 and I find it odd that they would change subsequent models to NOT have this feature. To increase/decrease the amount of light, there is a rheostat thumbwheel that has to be adjusted. That same thumbwheel also dims the speedometer for better viewing at night. Granted the buttons do certainly light up but they should be a tad brighter. I've had my car for so long I memorized all the buttons!!!

'05 Prius headlite outage by russ41
Sep 06, 2009 (9:05 pm)

Bought new, 8/'05. 55k. Noticed recently that the right headlite was out. Not just high or low-both. I usually run with the headlite switch in the "on" position as they automatically go out when car is turned off and the door is opened. Assumed bad bulb but as I was looking for a way to get into it, I cycled the switch and they both came on. I rechecked and sure enough, when the car is "on", the right lite is out. When the car is "off" they are both come on. Any thoughts?

C'mon people-somebody must have a clue as to where I might start trying to find out why this thing is acting this way. There has to be someone out there smarter than me. Thanks for any input. Russ 41.

I had the same situation on my '07 HID Prius.
The NHTSA has investigated the claims of BOTH HID headlights failing while driving.
All they found was ONE light out at a time.
They closed their investigation.
I had an intermittently functioning R-H side ( passenger ) HID headlight.
I took it to the dealer when it was hot under the hood and they told me to come back so they could "diagnose" the HID system. They could 't get it to malfunction since the lot boy shut off the car after parking it on the lot. ( After I told the NOT to ).
So I picked up the car and before I reached the edge of their driveway, the light was out.
Anyway, I took it back to them ( 3rd time ) and they replaced the HID "burner" ( bulb ) under warranty.
They told me it was a $400 repair. The 1st service writer surrendered when I initially presented the car for repair. She said it was "probably a bulb, and they didn't stock that part". What a JOKE!
That was over a year ago, and so far everything is still going strong.
