Please post feedback on which type of bulb and color temp you chose.

I have BRZ headlights with Morimoto D2S bulbs (to my surprise, direct drop in with D2S ballasts) at 5000k. They're nice.

D2S bulbs will require you swap to D2 ballasts. If I'm not mistaken, and correct me if I'm wrong, the BRZ/GT86 uses Matsushita ballasts, so you'd just need to find a set of D2 Matsushita ballasts to swap over.

The pickings for D4S bulbs are slim. I've been contemplating grabbing a set of D2 ballasts so I can run some Osram CBI bulbs. I have a set of those in my wife's Accord w/TSX retrofit and my goodness is it lovely.

Yep.. I've been thinking of getting a set of D4S bulbs but they are very pricey.

The Phillips are going for over $200 for JUST the bulbs.

However the Morimotos are a much cheaper alternative. Does anyone have experience with their D4S bulbs?

you can get a set of phillips bulbs on theretrofitsource.com for $95. The main difference between D4S and D2S are that the D4S are mercury free and are more environmentally friendly, they are a bit brighter however if you have a higher wattage output ballast the light output won't be too big of a difference between the two.

Im looking to upgrade to the osram bulb, too. Why is d2 matsushita ballast required? could you use something else i.e. morimoto elite 35? Or even use the oem ballast and somehow find an adaptor for the d2s bulb and d4s female ballast output.

You can use whatever D2 ballasts you'd like to use. I'm just saying that the Matsushita ballasts that Subaru has historically used have the same (or nearly same) mounting points across their entire range of ballasts, from old revisions to new revisions. That means you can swap ballasts and use the same mounting points on the headlight housings.

There is no way you'd be able to "adapt" the D4 ballast to use D2 bulbs. They are not compatible and trying to do something like that may end up killing you or causing a fire.

I'm currently running Morimoto D4S 5000K bulbs. The light output is great and the color temperature is spot-on. The bulbs themselves come with a 2-year warranty as well. I've also owned a set of H11 5000K bulbs & ballasts from Morimoto/TRS and the quality was excellent, and their costumer service was equally top notch. I'd highly recommend them!

yeah, i found out that the d2 and d4 aren't interchangeable after a long session of digging last night. Matching ballast sounds like a good plan, ill definitely look into it. thanks!

You're the first person that Ive seen with RTS' d4s bulb. I was looking at those too and trying to justify the upgrade over my stock bulbs right now, which would be little or no lumen increase. The change in to pure white rather than warm white sure is tempting though.

I've replaced my stock bulbs with Philips D4S Ultinon 5000k and they are brighter than stock with just a cooler white than the warm white the stock one's produce. Paid $250 for just the bulbs. I'm thinking of moving to 6000k version next to match my 6000k turn signal bulbs and selling the 5000k. I want to match my bulbs.

would you happen to know how they compare to the philips d2s 85122+ bulb? Ultimately i plan on getting the osram d2s bulb which is about a hundred cheaper than the ultinon, but it's just the bulb alone.
