Hang on… PM hatemail on the way…
Not the best, especially if you switch to harder-driven filaments like the H9, but not terribly inconvenient, either.
You never lost an alternator on a long trip, have ya?
I literally got back to the end of my block and was just trying to back up maybe 50yds before everything just upped and croked on me.
Then again, I was running 90W/130W H4s in 4×6 format lights…
For headlights, absolutely.
Especially the last one. What good is it to throw twice the lumens as the original filament, only to have most of them scatter and be lost, or worse, throw light where they shouldn’t. Think of glare to oncoming cars, getting tickets, etc.
All the other LEDs I put into my cars, at least match and in most cases outperform the stock hotwire bulbs. Side-markers are as bright as I can get ’em (and still fit), turns/tails/backups are all brighter than the original bulbs.
Then again, they’re meant to scatter light in a wider swath, for maximum visibility. So just go for power. As I mentioned, I had great luck with the JDMs I’m using, and “standard” 194s in yellow and red can be had which are way brighter than (filtered) hotwire 194s.
My only complaint about “dual filament” LED bulbs (xx57 replacements) is that the difference between low and high is a paltry 3:1, so parking lights are wonderfully bright, but turn signals are only a smidge brighter, visually. I’d rather have them turn down the low setting to have maybe a 10:1 difference, so that the turn signals will stand out more.
