reversing bulb replacment with LED bulb.

[chrisb]

just a quick question i plan on replacing the 7440 16mm wedge bulb in the reversing light on my car with LED bulb. anyone done this already?? either 18, 24 or 36 LED's? i'm after something thats brighter than the stock ones but not blinding...

Always the problem is timing on these things. I offered a group buy of LED Lights from Singapore awhile back. But someone mentioned fleabay was way cheaper.

My stuff is proven quality as I have them on my ride.

Mine are the 48LED ones as per:


When my father came over, I brought in some sets of these. b3n87, cjsig and criteek were the only ones who asked for them.

[chrisb]

ok cool i think i will get 36 ones. thanks ofey.

When reversing into a dark alley space or corner lot, These are absolutely phenomenal!

how much?

[ofey]

They were about A$32 a pair but I have none left. All sold. Only 3 people asked for it and I got it for them. Get some off Fleabay.

I only buy my LEDs from there. After bad experiences from Fleabay LEDs. Absolutely top quality!! I have my car fitted out to the max with LEDs from them.

I can vouch for these guys too... I have ordered some stuff and am very impressed with the service.

I had an issue where one of my numberplate LEDs is blue not white and they are sending a replacement set out asap and I am just going to RTS the old ones back. Great service, but I didn't notice abt 36led ones on the site.

those are nice and bright! I might have to pick some up from brightlights.

7440 T20 reverse lights yeah?

[SIR-VRX]

T20, yes. Make sure you get white ones too

[billyboy]

Recently bought a set of the SMD LED type off jpwarden (ebay seller), yeah they're the T20/7443 globes.

Put them in & pop it in reverse, LED's come on ok but just turn off after 3-4 seconds!

Any ideas whats going on? something's not happy.

edit: this is the sucker:

[SIR-VRX]

I have some red ones form the same seller, for my tail lights (only T10)

Try reversing the polarity of them. That should fix it. (The way the bulb is plugged in, so rotate it 180 degrees in the socket)

If not, they are faulty by the sounds of it (do both of them do it and at the same time?)

[billyboy]

Yeah mate, both shut off at the same time. Reverse polarity dont come on at all & shouldnt.

Funny thing is when I only plug 1 side in (with stock bulb in the other) its fine, but 2 together I have this problem.

Just occured to me I have my reverse sensors power tapped off this circuit, think this may be causing it?

[SIR-VRX]

Ahk, I know that reverse polarity normally doesn't allow them to come on for obvious reasons, but mine I have from him do. I was like WTF!! then I figures there is probably a circuit in there for it.

I would say add a resistor to it, either a load resisotr designed for it, or like ofey has used, a 180ohm wire wound. That should add a load similar to a globe. As I think that is the problem.

[chrisb]

were would you put the resistor?? would you need two or just the one cause the two lights are linked??
just bought some and the same thing that billyboy mentioned above is happening to me.
