Are these Bosch 9012 HIR bulbs real HIR ??

[Alaric Darconville]

Update on these, the +120 burned out in about 8 months, which was about 8000 miles, no clue how many hours it was, as the low beam on my vehicle are my DRLs.

I'd move the DRL function to the turn signals with the DRL-1.

I replaced the burned out one with a +50, couldn't tell a difference with the aged +120 vs the +50 as they shined on the garage door.

You would through instrumented tests. Also, it's easier for us to tell differences in intensities between two lower light levels than between two higher light levels. The difference is ultimately meaningful even if we don't think we see it.

I will just stick with the +50 as they are easy to get.

They'll last a bit longer, too. But that DRL service is killing your bulbs.
