Does anyone know if any companies are offering LED reverse lights for the GC? Also, has anyone had problems with hyperflashing or anything using LED turn signals? I am thinking of picking up the dual ones from Diode Dynamics. Thanks in advance.

I have NO IDEA what the significance or validity of this information is that I am about to state as I am not a mechanic, let alone a GC specialist so take this info as you see fit.
I was at the GC dealer regarding an electrical problem which turned out to be a loose fuse & while hunting down the problem the Hyundai mechanic asked if I had swapped out any of my light bulbs. He went on to say that they are constantly dealing with electrical issues caused by leakage currents, voltage drops, and other such problems that are cause by the use of bulbs not designed for the GC.
This makes me a little cautious about going to LEDs or other type bulbs. I don't want to end up back trying to chase down electrical gremlins.
I know a lot of folks are changing bulb types so I'm taking the wait & see approach.

Ya I can see what you mean - I might just go with Silverstars for my bulbs I am unhappy with. They have always been good to me. Does anyone know if it is safe to use 32W fog bulbs instead of 27W?

yes there are many companies offering LED reverse lights for the GC.
Here I am listing urls which is useful to you

Thank

I'd be really careful on that one. More and more vehicle manufacturers are using cheap, thin wiring to cut down on costs. So if the stock bulb is a 27w, some install wiring that can only handle 27w MAX. this poses a problem even with OE identical bulbs with the stock wattage. Bulb manufacturing isn't an exact science, and the actual wattage after production can fluctuate. per regulations, a 55w bulb has to be between 54w and 59w. If you end up with a higher wattage bulb, though still within regulations, and there's a power surge on that cheap wiring, it can melt or overheat your wiring. So I personally wouldn't take the chance running a bulb that pulls even larger amounts of current. You'll probably be saving yourself money in the long run by spending a little extra up front and buying some high performance bulbs that produce an increased amount of light off the standard wattage.

Ya that is a very good point - I guess I can look into the wires if they are one or two gauges above whatever a 27W max is then it should be ok. LOL, whatever happened to designing things to a safety factor .... ?

saving money suddenly became much more important. I would be interested to know what the true gauge on the wiring is in the Genesis.

This is why there's such a huge debate in the plug industry over using high performance parts. You've got guys that insist that the OE plugs were tested to be the best for the engine, and you shouldn't use any other. Not realizing that this cutting corners thing is such a huge practice these days

Wiring on the GC seems to be OK for slightly larger bulbs. Not near the reduced below par needs that the US manufacturer's use.

But the real backup lamps are already so lame why would you want to use LEDs? I have used a fog light fixed under the trunk floor and connected to the backup lamp circuit with a relay before on other cars. Only way to get bright usable light when in reverse.

+1......I agree. I replaced my BMW tag lamps with LEDs, but they are just not that bright & neither were the factory ones.
