They work just like the stock bulbs.

I took a shot because the GE Nighthawk, Sylvania, KC, and others were substantially more expensive. I checked (headlight revolution) reviews on youtube who said these are the same as United Pacific 31400 (had a decent review) Installed easily-no clearance issues in the popups on my 914. Some experience flicker with LED conversions, these flicker a little now and then at idle but it is not too noticeable. Brighter than HIDs on my other car. Wide spread and reasonable cutoff. Very satisfied.
