got my G4 5w bulbs...now for the g4 socket to get here so I can epoxy them into the reverse light  2014 FF Autobiography 5.0 SC
2008 FFRR (sold)

Anyone know just how large a bulb you can get away with,i know it is listed as 6w but others have put much larger ones in ok but if it connected to the trailer reversing cables surely it has to cope with what a trailer bulbs use.Just thinking of some extra reversing light possibly mounted in an inconspicuous place as just below the bumper .

All the trailer lights are fed through a relay so there is no drain on the wiring of the car........ but that's not to stop you using a relay to power your extra lights  Yesterday I couldn't spell Engineer... Today I are one!

As well as my brighter original reverse lights I also have a pair of supplementary led spot lamps mounted below the rear trim below the rear bumper. I have these wired through a pair of relays such that when I select reverse in daylight only the original reverse lights light up, when I have sidelights on the supplementary spot lamps also light in addition to the original.
You can't have enough light.
If you fit supplementary lights I would recommend wiring them through a relay and not directly off the original wiring so that no problems arise. Switch the relay from the existing reverse lights wiring.

Just upgraded my reverse lamps with the G4 ones, picture below is a before & after, bulb on the right is the Hungarian 21w lens melter, (I added an extra rubber ring to prevent melting) on left is the G4 bulb, ordered bit from bay of E, literally is a ten minute job (as long as you can solder) snipped of the old bulb carrier and soldered on the new socket, bit of heat shrink over joint, all done, really good instructions earlier on in this thread, look better in real life than the pic, really bright & white, worthwhile mod.

Well I liked the two sets of pcb's upgrade so I set about it,

The splitting of the units was so easy it's a surprise they don't fall apart

Finally got delivery from posty from China today 3 weeks later

So I decided to use push in bayonet holders from indicators as these with a small O ring fit perfectly into the rear of the lens.

I had some wired connector tails so will just upgrade the car wiring.

So here is some pic's before I go and fit them on the car

Just a quick update, decided to fit three of the G4 LED lights to each side. EXCELLENT results Pics below...
After checking all three lights worked i hot glue gun’d the wiring etc over the top so the vibration of closing the lower tailgate would not dislodge the plugs. Also bent the two outer tops over to gain more access to refit the light unit. Worked a treat

The biggest problem with those is there will only be enough room to fit 1 bulb per light..... and there is a restriction in the lens that will make it impossible to fit a large bulb, it wont go through the hole So your then limited to narrow bulbs that will be considerably less power than what is fitted at the moment

The only way to get a decent light output is to split the light unit and fit the flat led panels.... it does sound quite daunting, but, in practice is a lot easier than it sounds  Yesterday I couldn't spell Engineer... Today I are one!

I added some of these to mine



Four per lamp

Works pretty well, might be a too bright in some cases.
