Brake light prob.

[Qshipsta]

Hey guys, about a month ago one of my brake lights went out, not only did it go out, but it melted some wires on the circuit board,i've since replaced the circuit board, but my display next to the tach. says there is still a brake light out,what gives?

[PalmerWMD]

Did you use non OEM replacement bulbs?

Fred..

[Qshipsta]

well,. no i think i used oem,. i went to autozone, and they looked it up, then lead the way to the bulbs.,.

You'll need to get bulbs from Infiniti. Aftermarket bulbs aren't made to the same "standard" and don't allow the system to get the proper reading to turn the message off.

I have a similar problemAbout a month ago, suddenly the brake warning light came on. It is on whenever I step on brake. First, I couldnt find anything wrong but I realized that the taillight wasnt functioning. I don't know how to change them. Should I change them or take it to the Infiniti dealer (I guess this is the only option referring to the previous messages)?

I highly encourage you to read your owner's manual. If you don't have one, might see if you can download one at http://www.nissan-techinfo.com/infiniti/. Ebay may have some dead tree versions available.

I have the owners manual. But it says, see you dealer while changing this bulp.

[maxnix]

Which "bulp" is it? All are easily accessible. Perhaps Infiniti is afraid owners will use non-OEM bulbs. I will check my manual.__________________Brian1995 Q45 & Q45t & 2000 Q45

I dont even know how to remove the light since it is not in the manuals. they are not in that website either. If someone can tell me how to remove them, i can give you the bulp number.

[Qshipsta]

wait,. are you talking about the taillights EXPERTIE??

[expertie]

i checked the lights last weekend. they r all ok.but my brake warning light is on when i step on brakes.I am gonna take the car to a mechanic maybe i gotta change the brakes.

The closet easiest to find bulb to oem [Toshiba] are the Sylvania LL [long life].......inexpensive chain store bulbs even Slyvania regular have low quality bayonet tips which melt/soften under load causing problem with the sockets.

[elwesso]

Suck it up and get new bulbs and sockets from Joe.... Total cost of like $10-20

Thats one of the things thats coming with my winter jobs!!

[Qshipsta]

ok,. i got ahold of a set of the toshiba 1157,. or w/e they are,..they are stock for my Q45,.,.. they all appear to be good,. i've changed them and my display STILL say"STOP LAMP INOPERATIVE",..i don't know what else it could be,. i don't think it's the bulbs because when one of the bulbs did go out it read"TAIL LAMP INOPERATIVE",.,. any more ideas??

[911/Q45]

Tighten the silver Phillips screws on the socket assembly.

[elwesso]

You should also replace the socket assy too...... Thats what causes the message....

[Qshipsta]

Well,. i just recently replaced the whole circuit board for the brake lights,.,..is that what you mean by the socket assembly ELWEESO?

[elwesso]

You can get the socket assy (the thing that you put the new bulbs into).... Im gonna do that here really soon, as soon as I drop my bank account into infiniti of scottsdale for my projects...

What circuit board are you talking about....? Just to verify that we are on the same page, are you talking about the stop lights on the very rear of the car, or the high mounted stoplight in the interior of the car.....?

[Don Keyballs]

Couldn't you measure the resistance from the center conductor to the outer casing with a meter? You should be able to see if your socket is defective or compare the resistance (center to outer case) on the light bulbs to see if it is a bulb.

[elwesso]

Or you can just tell by looking at it..... If the area around the bulb socket looks like its been burnt (slight browness) that means they are done, or near done..... Its only like $5 from Joe......

[Qshipsta]

ok,. ELWESSO,. i'm talking about the rear lights,. and i think we are talking about the same thing,..socket assy.-circuit board,.,. the bulbs are good,.and OEM,..,. i'm thinking it happened ,. when the original circuit board-socket assy,. burnt out,.are there any sensors that could've been broke?

[zfixxer]

brake lamp in-op message on while depresing pedal and all lamps illuminate ?? first check the high mount bulbs, they must be 18 watt. and try to bend the contacts inward a bit in order to snug up the cotact to the bulb itself. also the Q is equiped with a tail lamp sensor (located in the rear cargo area). two things 1 a melted solder on one or more pins ( on the board itself ) this can be easly repaired but may require a magnify glass to spot it. 2 a burned diode on the board. this will require replacment of the tail lamp sensor.

[Qshipsta]

ok,. i'm thinking it must be the sensor,. cause the board is new,.,. what do you think a sensor runs?? is it difficult to replace?

[Qshipsta]

oh yea,. and it's not just when i push on the brakes,.it displays the message all the time

[elwesso]

I feel the pain.... I'll be watching this, as I pray the new sockets will fix it!!
