I was under the impression that LEDs had a very long lifetime. It hasn't been a year and I'm already on my second pair going on the third. Of all 5 of the little leds on each bulb, they don't all seem to fail, just a couple, which makes them blink on and off.

mine have been in for 2 weeks now, so far no problems.....maybe midgetfinger can chime in on this..

I have had same issue. Worst part is that when one or two of the 5 led's go out on one of my city light led units and the other unit is still burning all five led's then each city light emits at a slightly differet shade of light.

I think the longevity of the five led bulbs on which the led's are set up so that one faces forward and the other four are mounted "in orbit" around the center led pointing outward 90 degrees compared to the center led is affected by the fact that the total diameter of the opening needed to pass that type of bulb through in order to mount it is slightly larger then the diameter of the opening normally associated with a BA9 mount. You can squeeze the "4 in orbit" 5-led bulb through that type of opening, but I think the process damages the led's mounting apparatus and I think this results in a shortened lifespan for the bulb's individual led's.

They're so inexpensive though that I usually order two or three pairs at a time.

Long story...

Same here. Technically they should last longer but quality sucks. I need to find a better supplier.

I shaved down the tips of the 4 LEDs in orbit and it goes thru just fine afterwards, so I'll keep you posted on whether that works or not, cuz by shaving the tips down and having them go thru the housing without any force, I am sure that it doesnt get damaged, unless I damaged it when i was shaving it down?

On mine it keep burning but after I the took the resistor out, it stops the problem

midget fidger

My car was sold last year so I dunno how the bulbs are doing

halik

same problem here ... i wonder if its the resistor or something.

CurYousGee

how soon are you guys seeing failure? months or weeks?

I got mine from Ultraled in the UK. They cost a little more and take a little longer to get here but their quality is top notch.

what do i use to grind down the nub on my ba9 citylights? sandpaper or something? ne other options??

CARLSS0N

Just use the floor .....

DevilsAngel

all i can say is...gotta love those German cars. there's always something. and no matter how expensive they are to fix, i can't seem to stay away from em.
so any idea how quickly they've been going out?

CurYousGee

i just used the garage floor to grind it down, sand paper works, its been over 10 months now and some of the LED has gone dead, but enough of them still works...so far so good, but well see how much longer it last
