Updating headlights on older Prius?
« on: January 09, 2020, 09:09:04 AM »
I have a 2008 Prius that is still going strong, but I am noticing that as the car gets older (and I get older) the headlights don't illuminate the road and surroundings very well.  I am not a car person at all but imagine there must be a way to brighten them up.  I tried to google this and was immediately confused by the assumption of a knowledge base that I don't have (halogen, LED, capsules, Xenon).  I'd appreciate suggestions on what to do/buy.

Buy a headlight restoration kit and follow the directions. It'll be less than $20 and they work great. The UV coating needs to be restored.

Are the headlamp lenses cloudy and yellow-ish? If so, that's something that can be polished out and re-done at a few various body shops in your area for around $100-200. You can DIY as well, but it takes a lot of patience and skill to do it right without making it worse and potentially having to replace the entire headlight unit proper. (Ask me how I know this!) Better to pay a pro with experience the extra money to ensure good results, and then just stay on top of keeping the lenses regularly coated with Meguiar's Headlight Coating as a sacrificial UV/oxidation layer to keep it from happening again.

I believe the 2008 Prius had HID headlights.  I recently learned that HID bulbs degrade significantly with age, which I discovered when I bought a used 2017 Bolt and nearly immediately noticed the headlights were flickering and occasionally turning off.  When they did manage to stay on, they were far dimmer than I would've expected from any modern car.  I replaced both HID bulbs and now the lights are bright and flicker-free as I would expect.

Assuming it's not something you have done yet, I would start by replacing the HID bulbs.

Replacing the bulbs and cleaning/restoring the glass would be my first attempts. I highly recommend watching this video on headlight upgrades:

Wow. That was extremely informative. I had no idea.

Just a little cloudy. I'll try to polish them myself but won't take it too far. And good to know about the headlight coating. I ddin't know they made that type of product.

Looks like I'll start with the polishing up the glass and then maybe changing out the bulb if I still think it needs improving.  Thanks all

The brightness jump from going to new bulbs in my car was astonishing, and it's a 2017 with 58k miles on it.
