Did replacing the bulbs actually fix the problem on the Prius? For how long? I'm wondering if the ballasts need to be replaced as well.

Yes, for me it fixed the problem of the lights going out. No need to replace the ballasts. Good luck!

I used them on my VW bug, they are just the low beams. After see the answers given by the other to customers here, I went out to my VW to double check the they are just the low beams. My car has two different bulbs in the headlight one for low and one for high. This replaced the low beam in my headlight. If you look them up on amazon at the top of the page is a compatibility tool. If you enter your car info it will indicate whether they will work for your Prius. They are just bulbs without a housing so I would imagine they will fit many cars. I have used them for months and they are great nice and bright and clean white color.

This is a good ballast unit. I haven't had any trouble with mine, however it is something that can break down. The fan needs to be on to cool the unit. Have you plugged in the light swvith? The plug goes right in the front . If after you plug in your unit and it does not work you need to call the company you bought this from and ask for a replacement. Hope this helps

My light recently stopped working after 2.5 years of daily use. I replaced the bulbs but that did not work. Usually this is a sign that the ballast needs replacing. I can't find it however even after removing the ends and looking down the tube. Before I take it apart any further I'd like to know if anyone else has done this repair successfully. I contacted Hydrofarm. I have not yet heard back. Here is there support page: https://www.hydrofarm.com/support

No my drivers side went bad first them 3 months later the passenger side went bad. To test just unplug one side and plug new one in before you remove the old one, turn on the car if the light does not go off try it on the other side. If still doesn't go off order another one.

This seems more like a power issue than a ballast issue. Especially in the case of your subs turned up. It also depends on how your ballasts are connected... (meaning to the factory headlight wiring or through a relay which provides direct power from the battery.) The relay setup is the better option as sometimes the factory wiring isnt able to carry the amount of amps the ballast require, especially at startup which is the highest load. You can take a look at this to see if it resolves the issue before replacing the ballast. My second recommendation is an addition to your music setup, which is a farad capacitor. This will act as a power buffer for when your sub is turned up. You can check youtube to have a better understanding of a relay setup for you ballast. And also how to integrate a capacitor into your music setup.

you probably only need to replace the bulb socket and ground screws.I did that to 12 of them not long ago and they are working fine now.

Your ballast and capacitator need to be replaced. Although the lamps last forever, the current manufactuers of ballast are junk. Best to replace whole light as cost to have someone replace ballast is probally more than cost of new light unless you have a friend who's an electrician. I have had to get three replacements in last 22 years. The last two only lasted 4-5 years a piece. Neighbors have same problem. Hopefully you can get your money back for the bulb and photo cell.

Yes it is Richard. There is a small problem with main rubber gasket. See my review Dec 2014. I contacted the company and advised them of the small problem and they may have fixed it. If not you can still make it work. Do not throw away the old lights incase you have to switch the rubber seal for main bulb.

CHECK all cords make sure you have right power and switched right then 100%to start.If that don't work send ballast back. they have bin really good replacing bad or defective.

I'm not sure, we live in Texas, we have not experienced any problems with the ballast, but the problem would be with the bulb warmup time. Good luck

I think that the bulbs are the same, , , the ballast is what decides the brightness. Don't take my word for it tho.

From what I'm understanding, it sounds like you have not purchased any HID ballasts. In order for HIDs to work, you need HID ballasts, HID bulbs and a way to connect them (such as this harness).

How long did the last? What model did you install them on? My answer is if you installed them and they malfunctioned upon installation then you got a defective pair. In the meantime, I'll tell you that mine work really well they get the job done pretty well... However, I have gone through 3 pairs of these because I'm constantly turning my lights on and off (it's my daily driver). However, these LEDs do give my car a modern look :) Hoping to hear back from you soon so I can properly reply.

If the bulbs you are replacing have the same electrical contacts (the part of the base that plugs into the socket is the same) then it will work fine. No ballast is needed (plug & play, so to speak). The original incandescent bulbs in my BMW would burn out repeatedly after about 400 miles. I have had these bulbs in for nearly 10,000 miles with no issues.

Changing the circular bulb is one thing. Getting and changing the ballast quite another. I would suspect that the cost of replacement may be close to the cost of a new mirror. Doing it yourself is not always successful and therefore you could loose your entire investment and the time. Get a new mirror.

Hi. Put them in days after buying and after a lot of night driving no probs at all. Might suggest that if you are having problems with bulbs blowing may be something electrical with car?
