led tail light bulb problems

[9blazer8]

alright i ordered these 12v led bulbs for my 98 blazer well i just got them today and they dont work in my tail light socket but will work in my reverse bulb socket so why is that ? ive been all over the web trying to find out why before i send them back

you need dual filaments if that what you mean

[9blazer8]

whats that mean? i got them off ebay for a decent deal i had to order four of them there 35 led a piece.

35 dollars? well tail lights have to be dual filaments and front turn signals because when you flick you lights on they will be at a sorta low level. then when they are used say apllying the break they will get brighter...

im a little confused on what you mean they dont work...do they not fit? or not light up?

[9blazer8]

no they have 35 leds in each bulb, well i bought them thinking they would work there the right size i tried rotating them around but no luck they dont light up at all untill i take out my reverse light out of the socket then install the led bulb into that socket then it works great. i was thinking it could be needing a resistor on all four of the bulbs in order for them to work... now i thought maybe its the bulbs but i have white led bulbs for my reverse lights so i just took them out and installed them in my tail lights and they dont work either. its werid

uhh id have to say wrong bulb size because usually a reverse light isnt the same size as the taillight. unless im wrong i didnt look up your bulb sizes. i know in my car they are different. even though you may need resistors i have leds in mine and they work just give me the light out indicator by blinking fast.

well these are the ones i bought but these are 48 leds i have 35 leds.... http://www.ebay.com/itm/2x-3157-Super-Amber-Yellow-48-LED-Wide-View-Angle-Tail-Light-Rear-Lamp-Bulb-12V-/251065277000?pt=Motors_Car_Truck_Parts_Accessories&fits=Year%3A1998%7CModel%3ABlazer&hash=item3a74a81a48&vxp=mtr

well in specifications it says dual filament...so i honestly dont know without seeing it. because you said it worked in the reverse lights? and you put them in both ways?

[9blazer8]

yeah thats why im lost im not sure why they wont work, but yeah they worked in my reverse sockets there super bright to and i just bought these clear tail lights no red on them to make the bulbs look red but i had clear bulbs in there here in michigan and probably every state the tail lights have to shine red or with red flim on them. i contacted the seller on ebay to see what they will do they have really good feedback so hopefully they will help me

[lowsound10]

yeah i hope everything works out for you man. i mean mine work great and are bright as shit. got some in my front turn signals, reverse light and licence plate light. i took my tail light ones out for now gunna get different ones.
