Frequently Asked Questions (FAQ)

Kas yra W5W ir P21W lemputės?

W5W – maža kapsulės formos lemputė (5W, T10 cokol'is), naudojama gabaritams, salono apšvietimui, numerio apšvietimui. P21W – vieno filamento lemputė (21W, BA15s cokol'is), naudojama stop signalams ir posūkiams. P21/5W (BAY15d) – dvigubo filamento, kombinuotas stop+gabaritas vienoje lempa.

Ar verta keisti gabaritus į LED?

Taip – LED gabaritai (W5W) gerokai šviesesni už halogeninius, ilgiau tarnauja (25 000+ valandų) ir mažina elektros suvartojimą. Bet daugumai automobilių reikia CAN-BUS adapterio – be jo gali rodyti „lempa perdegusi" arba mirgėti. Patikrinkite suderinamumą su konkrečiu modeliu.

Kuo skiriasi P21W ir P21/5W?

P21W – vieno filamento lemputė, naudojama tik vienai funkcijai (stop, posūkis arba atbulinio važiavimo signalas). P21/5W – dvigubo filamento (21W + 5W), naudojama kombinuotai (stop + gabaritas vienoje lemputės padėtyje). Skirtingas cokol'is: BA15s vs BAY15d – nesumaišykite.

Ar gabaritai turi būti baltos spalvos?

Pagal LT eismo taisykles – priekiniai gabaritai balti, galiniai – raudoni (jie yra po raudono stiklu). Salono ar numerio apšvietimui baltos – privalomos. Spalvotos LED (mėlynos, raudonos) priekyje neleistinos – už tai galima gauti baudą per techninę apžiūrą.

Kiek kainuoja LED gabaritų rinkinys?

Pradinė klasė (Bosma, generic LED): 5–15 € pora W5W lempučių, 10–25 € pora P21W. Vidutinė (Osram, Philips X-tremeVision LED): 25–60 € pora. Premium (Osram Night Breaker LED): 60–120 € pora. Su CAN-BUS adapteriu, jei reikia – pridėti 10–25 €.
