Yaris Hybrid headlights - swap H1R2 for HB4 and bingo!

10 posts in this topic

Hi all,

My wife has recently bought a 2012 Yaris Hybrid which we both love.  However the headlights are... shall we say... a little underwhelming :rolleyes:

I've found a way to greatly improve the Yaris Hybrid H1R2 headlights - fit modified HB4 headlight bulbs!  Basically HB4 and H1R2 only differ in having slightly different plastic lugs for mounting.  More importantly, for some reason, there are +110%, +130% etc versions of HB4 whereas there aren't for H1R2.  Therefore with only a small modification to a lug, you can safely fit an HB4 such as this:

https://www.amazon.co.uk/OSRAM-NIGHT-BREAKER-UNLIMITED-Headlight/dp/B00FQ8ANTE/ref=cm_cr_arp_d_product_top?ie=UTF8

This is a Nightbreaker +110%; the reason I include this link is that it includes details of the modification - look for the "top customer review" regarding their use on the Vauxhall Ampera, which suffers from similarly rubbish H1R2 lights.

Now my Ampera and my wife's Yaris Hybrid have far better lights, using the Halfords +130% HB4 bulbs which are always on buy one, get one free :)

Hope this helps...

Richard

This isn't new and has been covered several times before over the past three years or so.

HIR2 bulbs are approx 75-80% brighter than standard halogen bulbs. Halogen bulbs, includng HIR2 bulbs, deteriorate with age.

As the HIR2 bulbs in your Yaris were 4-5 years old and would have deteriorated in that time, the difference in brightness between the existing bulbs and new ones (whether 9012 or 9006) would have been noticeable.

Ok, thanks, I hadn't realised.  Primitive searching through Google, and looking through various threads on here didn't seem to indicate that anyone had come up with this alternative (which I don't claim credit for in any case).

I hadn't realised that it could be age-related to be honest... I shall feed this back onto the SpeakEV forum (Ampera section) where this hasn't been thought about as a factor.  Thank you :)

The best option is to go to your local Toyota dealer and ask for part number 90981-YZZAM which is about £25. The other part number (90981-13062) is about £40. This will be the best fix as you are using a bulb made for the car and is still a HIR2 ! :-)

Thanks!  What's the difference between the two bulbs?  And why would they be brighter than a +130% HB4?

Cheers

The 90981-YZZAM is part of Toyota's Optifit range (Optifit are a range of lower priced parts) -  http://www.ebay.co.uk/itm/Genuine-Toyota-IQ-Headlamp-Head-lamp-Optifit-Car-Light-Bulb-HIR2-90981-YZZAM-New-/251389195893 

The 9098113062 looks like it is the OE bulb - http://www.ebay.co.uk/itm/Genuine-Toyota-Headlight-Bulb-Aygo-IQ-9098113062-/321783442803?hash=item4aebc9ad73

No difference in terms of light output.

That's what I suspected, thanks.  I'll stick with my higher-brightness bulbs then...

I recently did a search for HIR2/9012 bulbs, seems like Osram and Philips are introducing 130% blue versions of it. They are both made in Germany, but I find it ironic that only a few US sites are selling them, nothing from Europe or the UK yet. I am tempted to buy a set from the US to try it out.

P.S. Philips Crystal Vision Ultra 9012 / Osram HIR2 Cool Blue Intense

Strange that they're not around in the UK yet then.  If you do import some from the US, please let usk now how you get on...

 

Thanks

The Osram Cool Blue Intense are 20% brighter, and look like Powerbulbs will be stocking those (though not yet) - https://www.powerbulbs.com/product/osram-cool-blue-intense-hir2-single

The Philips bulbs don't seem to quote additional brightness - https://www.amazon.com/Philips-9012CVB2-CrystalVision-Upgrade-Headlight/dp/B01I3OTXH

HIR2 bubs are already approx 75-80% brighter than standard halogen. So a 20% brighter HIR2 bulb will be an approx equivalent to a Osram Nightbreaker Unlimited +110% in non-HIR2 fitting (eg H4, H7, H11, HB4).
