Led's

[justin911]

hey peoples

i was gonna get some colored LED parker lights to slap in my cluster today, the guy at autobarn said he recommened not to use LED's because it can interfere with the cars voltage... he said it can make it jump/decrease at random times..

I know theres heaps of people using LED's but does anyone know if what he was saying is true ? and if it is, how much would it make the voltage vary ???

thanks

i am using LED's for my front blinkers, on the fron bar, they work fine no problems, they just need to have the circuts built in for 12vdc.

i've had LED parkers for over a year now. I used the Narva ones. they're fine.

the guy at autobarn doesnt know what hes talking about, LEDs have a fairly consistant current draw, theres no reason for them to alter voltage

I've seen 2 threads in 2 days now with "the guy at autobarn said..." ...

LOL

[dezz]

there ya go justin! so go back get a refund on those dull shit globes he sold u, get the LED's and slap em in. you'll love it

and with the LEDs for the front blinkers, i assume they're just orange LED's ur using? are they just brighter than normal blinkers?

[justin911]

yeah but if it cant get enough voltage it will drop the line voltage..

least thats what an electrical engineer who design's LED's / those cool led signs you see told me today..

also the autobarn guy was telling me why people had returned them.. 2 seperate brands... the LED's were more expensive than the ones i got so i dont no why he'd be trying to con me into getting cheaper ones..

anyone done tests on the voltage on ya car while driving for a week or so just outa curiosity ??

nah im still looking for evidance there 100%

maybe they are and there wont be any problems.. just odd the diff opinions i've heard about them..

Led's are a great solution when replacing incandescent bulbs in many applications. One problem is that LED's don't like changes in voltage. For example, the voltage from a car battery can fluctuate quite a bit from 11 - 14 volts and this can be a big problem for an LED circuit. If you design the LED light for 11 volts then it will shortly become a DED (Dark Emitting Diode). If you design the light for 14 volts it will always be very dim when it is only gets 11 volts.

took that from some website.. theres alot of info on it on google, i probs should of searched there b4 coming on sau

another way to find out is to test them in your own car....dont listen to some guy from autobarn and some guy with a lancer

Ok, i think what the guy at autobarn may have been trying to say is that if your car has a warning light on the dash for when a globe blows.

It will be on all the time with LED globes because they do not draw enough current like a normal globe to make the warning light go off. (It thinks a globe is blown)

Unsure if the R32/33/34 have a warning light for blown globes?

R31 do have this feature.

im using leds as my dash lights, they are bright and crystal clear and dont create any voltage spikes, infact they use bugga all power full stop.... the guy from autobarn is pullin his pud!

there ya go justin. off ya go to autobarn tomorrow

if you mean led for alternator warning light then no you cannot use because it will not pass throught the fillament down to the alternator regulator to excite it ie cause it to charge

led's are great for lighting but not for warning lights because in some cases the globe will need to work both ways and with led's they are a diode so they only work one way in most cases

thats my two cents

ive had led dash lights and no plate lights fro two years no dramas at all

My experience, we fitted LEDs to a ute here at work, a custom rear light section with blinkers, stops, tails and reverse.

We noticed that the blinkers flashed really really fast like when you have blown one. We took it back and they said its because LEDs use a lot less voltage to operate than the normal globes ( as someone mentioned). We changed the flasher can to one specified and problem disappeared.

so are you saying it should work fine as long as you only put LED's in the dash lighting spots, and leave the normal globes for the warning lights?

thats the way i would have been doing it anyway...

the guy at autobahn talks from his arse

i have over 120 LEDs in my tail lights + resistors , from nismo conversion

and there is no such drop in voltage , LEDs consume such little energy that it has no effect!!!
