Becuri pozitie cu Led

Salut am incercat sa pun becuri cu led la pozitie si cand aprind pozitia palpaie. Am incercat mai multe tipuri de becuri si cu toate patesc la fel. Are cineva idee care ar fi cauza ?

Cauza.... Modul in care sunt alimentate becurile.
In afara de faza lunga si proiectoare, toate becurile de pe masina sunt alimentate in pulsuri (PWM) prin niste FET-uri din CJB (central junction box).
Un bec normal, din cauza inertiei filamentului, nu va palpai, dar un LED, da.

E posibil ca si sistemul de detectie bec ars sa aiba aici o influenta....
Intre pulsurile de tensiune, sistemul verifica continuitatea filamentului. Din cauza consumului mult mai mic al unui LED, e posibil ca CJB sa lungeasca "pauzele" de alimentare si acea palpaire sa fie mai evidenta.
Unele LED-uri au in paralel o rezistenta pentru a simula un consum mai mare, ca a unui bec. Incearca sa pui si tu una. Sau sa folosesti un LED din acelea asa-numite "CANBUS safe".

Salutare.
Eu am avut cca 1 an de zile niste leduri canbus pe pozitie (fata), care au functionat fara probleme.
Acum cateva zile am am observat ca nu-mi functioneaza pozitiile fata. Initial am crezut ca e o prb la sigurante, dar restul electric pe masina functioneaza fara probleme ( semnalizatoare, lumini interioare si exterioare, pozitii spate etc). Am achimbat becurile ( ce-i drept tot cu led), dar nimic.
Vreo idee?

Schimba si cealalta chestie, din partea cealalta a becului..... masina adica. Laughing
Glumesc, bineinteles. Laughing
