Brake Lamp Light On, but Brake Lights just fine!
About a month ago the brake lamp light on the dash turned on. I shut the car off and booted it up again and no brake lamp. Then it started coming on for a day, and not showing up for a week or so again. Now it seems its on all the time....
Will the dealership cover it under warranty and fix whatever needs to be done? Is there anything I can do to move the sensor or something to fix it, because the brake lights are and have been working just fine |
it's the sensor in the brake fliud resovoir. it happened to me too, just top out your brake fluid or adjust the sensor. I notice it happens when I hit a pot hole etc. the sensor is way too sensitive
|
Where is the sensor?
|
The sensor is inside the Brake fliud resovoir (cap)
Buy it from dealership. They will change it for you for free or DIY. It is really easy. I remember there is only two wires connected |

Also how the hell does the brake fluid reservoir cap sensor have anything to do with the Brake LAMP light on in the gauges
|
Also, there is a plastic ring (with the cap) inside your brake reservoir.
If the ring is struck or the sensor is failing, the brake lamp will be on. Finally, it could cause the brake calipers hung-up BTW, The Cap just cost you $30 |

I'll talk with Acura I guess if i cant fix it myself, and see what they say it is. This sensor isnt covered under warranty or the cap? |
I am not sure if the cap is covered
Just make a call to your local dealer, they will explain to you what's going on with your brake lamp it is a common acura car problem they told me |
Dealer replaced my cap and Acura paid the bill. I have a CL-S 2001 with 75K miles. The original stupid cap / sensor caused a problem every time the temperature fell to 40 degrees. :thumbsup:

They are double element bulbs. One side of the element can still work as the other side is blown. Go to your dealer, buy ALL 4 taillight bulbs for your car and install them yourself. They are very easy to install. That will turn off your "brake lamp" light.. good luck. |
why would you need to buy all 4 if only 1 is blown?
|
Cause a month later the other light will blow. You also have a different brightness between the new & old bulb.
When I have 1 bulb go out I replace both sides. Your already buying the bulbs, your already replacing 1 might as well do them all. |

lol...obviously you aren't understanding man...
there are 2 "brake" lights on the guages...one that reads "Brake" and another that says "Brake lamp". The "Brake" light is either for the e-brake, or the fluid reservoir. The "brake lamp" has to do w/ the taillight bulbs. |
Yes, it says "BRAKE LAMP" not the "brake" light.
My tailight bulbs work just fine, whats the problem? |
renegade...replace the 4 brake light bulbs...they're 7443 bulbs. I just did that and they work now.
|
The thing I don't understand, is if all the brake bulb lights work just fine when I'm braking, why is the light on, and why do I have to replace them?
|
someone above mentioned that they're dual filament bulbs...

Take them out and tap or shake the bulb while they're still in the sockets and the headlights on, then do it with the brakes on and you'll probably find one that flickers on and off. |

So when the light is off the drivers side brake lamp is working, but when its off one of the bulbs isnt working, hope its not wiring, and a replacement of the bulb will do, how do i get back there? |
I just noticed my red "Brake Lamp" light on the dash lit up. I checked my tail lights and the brake lights, strangely, looked fine. As posted by another member, the bulbs are dual filament so if one burns out you have one remaining filament in the bulb. This allows you the chance to replace it without getting a ticket for not having a working tail light (genius). Replace both and keep the other working one a as a spare. You can access them by unscrewing the larger notched black knob just behind the tail light housing in the trunk. There's one on each side. After unscrewing the knobs and pulling back the carpet paneling a bit you'll see a cluster of 3 light bulb harnesses. The brake light bulb is on the bottom. Just turn a 1/8 of a turn and it will pop out.

There are 2 brake light bulbs in each tail light. So when one burns out it still is lit up... It's actually kinda hard to see if both are lit.
This happened to me last week. Fixed it in 2 mins in the crappy tire parking lot with no tools at all |

Oh man was this so true. True story.... I drove around for a year with my "brake Lamp" light on, thinking I would get it fixed one via the dealer and it would cost me a fortune. Last week, I google the issue because I was prepared to get the issue resolved and it led me straight to this forum & section. after reading the comments, I decided to test out some of the theories. Lo & behold, it turned out o be just a burnt out bulb. A quick trip to the autopart store, $7 bulb purchase and issue has been resolved. Thank you for the info below. This information is soo true & accurate
