LED brake light bulb mystery


iwayman

Recommended Posts

I bought a pair of these LED bulbs a few weeks back with the idea that they will increase light output and decrease heat from the conventional bulbs.

With the bulbs installed for my brakes, as soon as I trigger the brake switch every exterior light comes on (headlights, side markers, reverse, brakes).

 

This does not happen with conventional dual filament bulbs installed.  Any ideas for what can be done?

there is something when you run leds you need to get that goes on the wires, led's put alot of strain on a cars electrical system, your lucky you didnt fuck up your harness.

 

Bubbish!!!!!  :lol:  LEDs draw almost no power so almost no strain on the electrical system. No way will they harm the system drawing less power.  Because they draw less you signals may not work. Older systems are load dependent, the more bulbs the faster it flashes. Newer ones are solid state and flash at the same speed. This post is about brake lights anyway not turn signals.

Check that the contacts are identical. Looks like those wide contacts (on the bulb) are bridging across the plug terminals and brakes will be powering the running light side.

I was at pep boys the other day looking at those same bulbs. They had the oval contact point bases and round contact bases. I'd try the round contact ones just because that's what the original bulbs are. I'm scared to try them now.

 

My dad got those LED bulbs for his '08 Ford Superduty, and when he'd turn on the turn signals, all the side marker lights would flash (dually flare lights) when they weren't supposed to. There was also the smell of burning electrical when they were on. Can't say why it happened.

I know plenty of people that have installed led's and fucked up their electrical in their older cars. Hell im one of them.

You should know better than to argue with King shit, he knows everything aboot everything, even if you saw it and had it happen to you    :angel:

 

All my lights are bright, even the dash lights, just be sure you have good grounds and the regular bulbs work just fine

LED's draw no power. What the fuck did they do to their own systems/
 

There is a load thing you can buy. but...  It's to help your system. Basically when you run LED vs stock bulb, sometimes your flasher will flash to fast thiniking the regular bulb is burned out, since the LED doesn't draw enough power.  You put those on, and it makes the system think its a regular bulb pulling regular power.

 

IDK why your friends had electrical issues. I have to disagree with the statement LED's have fucked up electrical systems. As much as I would like to agree with you.

 

PS, to the OP... Don't buy that over priced garbage :|

 

Much better quality at realistic prices. https://www.superbrightleds.com/

 

Some load resistors.

Read up on the website FAQ.  You can email them also for free support.  Ask them if they have ever had issues with LED's fucking up someones electrical in older cars just to be safe.

Could be that the contacts are clocked differently with respect to the bayonette pins.  Sounds like you're backfeeding 12v to a ground or switched hot, turning on relays...not really sure.  The fact that they claim to not trigger a CAN BUS error makes it sound like they already have a "load equalizer" built in.

I notice th same thing with the contacks they look long and may bridge the socket contacks,

 

the turn signal Blinker Cans use a Bimetal switch which heats up and thus makes the click sound also so it needs more current so the metal bends.I seen new solid state flasher units now than can be switched.

 

Im waiting fo soemone to try this and give a report back

Not the fault of the LEDs. The bulb sockets are cross connecting all the lights. There should be no damage to the wiring as everything is fused.

 

This makes sense, I will look into resolving it.

Fat discounts for working at a parts store  :rofl:

LED's draw no power.

 

 

 

If you believe this, I have a perpetual motion machine that you can have for a Million Dollars [American].  A "bulb" that draws no power CANNOT produce a light output.  PERIOD!

 

 

C'mon man really? You really think I was saying literally they were drawing absolutely no power?

Tim's exaggerating for effect. LEDs draw very little current for the light produced. Extremely efficient.

 

 

Haha, this guy gets it... 

 

LEDs on a turn signal draw so little power that sometimes the flasher thinks the bulb is not there or burned out and will cause a fast signal indicating so. You can get a little adapter to fix that from the site I listed.
