CHMSL / Third Brake Light LEDs

[eduardolalo11]

Is it the seat belt chime?

No. I have tried it with and without the seatbelt and it still has the chime at the end of the start up cycle. There is not a warning light, however there is a warning chime and I don't know where its from. do any of you guys know where it could be from?

I replaced the cargo lights with these; https://smile.amazon.com/gp/product/B01LX4FMD1/ref=ppx_yo_dt_b_asin_title_o05__o00_s01?

...and the brake light with this; https://smile.amazon.com/gp/product/B07JJZQWKT/ref=ppx_yo_dt_b_asin_title_o05__o00_s00?

Pretty slick. The cargo lights do show 2 yellow dots through the lens when the lights are off. This could be why they used clear glass incandescents (they're invisible from the exterior).

Sorry to resurrect this thread but I need some help here with a weird problem caused by swapping the bulbs.

I bought one of the sets of bulbs suggested in this forum and installed them tonight and they were great. Reassembled the assembly and screwed it back in and now the light will not shut off automatically. I hit unlock, light comes on, then stays on until I go inside and hit the physical button vs shutting off either with time or by hitting the lock button on the fob.

I thought maybe it was the bulbs causing it, so I put all of the stock bulbs back in and the problem is still persisting. Tried turning the truck on/off, cycling lights, etc...no luck. Any thoughts?

Parts installed initially:
Cargo light bulbs - https://www.amazon.com/gp/product/B01GGK6QDW/ref=ppx_od_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

...so I would like to update this for anyone who is as incompetent as I and anyone else who would like a laugh.

The answer to this was when I installed my lights and they turned on/off as normal, I was in my truck bed with the tailgate closed. When I was testing them after installation, the tailgate was open...which keeps the lights on. I did not put that together until the day after.

Reinstalled the new bulbs and all is well. The more you know

Funny! Had several I-D-10-T errors myself!

I bought these light bulbs https://www.amazon.com/dp/B07D1FVK93/ref=cm_sw_r_cp_api_i_Qi1rCbQ226CF6 and I don’t know if they are the reason why I have an extra/6th warning chime after my truck start up, I don’t know if it was there since brand new I only have 1000 miles on it? Anyone experiencing this please let me know your thoughts by the way it is not the seatbelt I’ve tried on and off and still does it please help!

FWIW, I bought these bulbs in October and one has already failed.

did you get the additional chime when you start the truck? like there is a bulb out?

if so can you post a video?

I really like those 3rd brake lights that flash 3 times and then go solid. I think I'm going to try out a red LED that's supposed to do that.

Have you tried this yet? If so and successful could you share part number used please.

 

[Gman]

I did...and part number is in a my post above. I like it a lot.

Do these lights over the bed illuminate when in Reverse? Only lights I get are tail lights. 3rd brake light does work when brake is pressed, and cargo lights illuminate when tailgate is open or doors are open, just not in reverse. Is that normal behavior?

Frankly, I don’t recall how it worked before I changed the lights out.

 

[Gman]

That's normal. Reverse lights are used when in reverse. You should be able to turn on the cargo lights using the switch in the truck.

 

[sgtsodo]

Thank you, it would make sense to me for the overhead cargo light to turn on in reverse!

 

[Nails]

If I need some extra lighting in reverse that’s what I do.

Did mine tonight with the $9 4 pack from Amazon. Happy with them so far. Wish the color matched the License plate lights a little better but a drastic improvement over stock halogens.

^^^ completely night and day from stock bulbs. For sure the best bang for buck mod I’ve done.

 

[MValdez]

Anybody find a solution to replacing the stock led reverse lights with brighter bulbs? I unscrewed one tail light and the unit seems to only have 1 fixture...

Just installed Diode Dynamics LEDs in third brake and cargo lights, replacing the crappy ones from Amazon. Glad to be flicker free back there again. Already had one burn out completely and one cargo LED was flickering like a disco light.

I went with the HP5 brake light and went with the HP36 cargo lamps. I was concerned they wouldn't be nearly as bright as the Amazon "1000 lumen" LEDs since they are rated at 210 lumens, but once installed these appear to be exactly as bright. I didn't spend double for the XP50 which they rate as twice as bright - 410 lumens. I'm totally pleased with the HP36 LEDs and the light output..

For reference, the Amazon LEDs were these (do not buy as they last about 6 months and then flicker and burn out):

I went through two sets of amazon bulbs, they are junk just like you described.
