LED dash bulbs keep burning

Dear friends

I put 4 different sets of LED bulbs in my clocks and after one month or less burned out one by one
I buy the cheap ones from e bay 3 euro 10 pieces and some expensive ones 12 euro 10 pieces.

My bulbs are T10 (w5w)
All after 20 - 30 days are starting to blink and die after 1-2 days.

I check the connections of the dash is good
I check the voltage of my battery is good. 13.2v - 14.4v
I clear the pins of the bulb socket to have the best contact

Am thinking to buy the expensive ones Philips but i guess i will have the same result..

Is there anything else that i had to check ?

Anyone has the same problem ?

Thanks
 
Yes is for 12v

Specification:
-100% Brand New
-Socket Type: T10
-Current:50ma
-Lumen: 80LM
-Voltage: DC 12V
-Wattage: 1W
-Size: 20*9.5mm
LED Number: cob 8SMD
Lighting Angle: 360 degree
Weight: 3g/pcs
Color：White
 
If you put LEDs in your dash then you need to change the resistor that comes with them as your car runs at around 14.4v and not 12v that the LEDs are limited to. Get yourself some 620ohm ⅛watt resistors and swap them. They'll last forever then.

Vibration, temperature shock and peak inverse transient voltage (PIV) range tolerances not stated therefore cannot be verified compatible with automotive instrument panel use and voltage regulation. Ebay/amazon tat from China cob8SMD not manufactured compliant to relevant ISO/EU standards.
In conclusion, suitability and durability is therefore unsurprisingly indeterminate as per your experience?

You're an electrician aren't you? That's kind of what I was trying to say but you actually know what you're on about haha

Dear agent thanks for the info
I do my search and is little rare the resistors 680 ohm 1/8 watt
Is there any other specs that will do the job?
Am not very good for electronic stuf but if i had the right info i can solder the resistors to the bulbs :)

You say bulbs, do you mean LEDs? You can use 620 or 680ohm resistors if so. There's loads on eBay.

Yes sorry i mean leds
But i quess i do not have space to solder the new resistor!


My last order are the above

The yello ones last only 3 weeks.
The can bus are comming next week
I bought onother 3 sets and the same luck.. burned

Ah I see. You can't alter those ones really without faffing about. These are the style/type you can alter. The led pulls out and the resistor can be swapped for a different value. They also do T5 ones of this type too.

I bought them exactly the same and they burn after 10 days :) also they produce much less lumens that the other led
I think i will stick with the white halogen bulb that came today !
