Put your hand over a headlight with a 55w HID bulb in there and you will feel much more. Do the same on the fog light and you will end up with a nice blister burn after touching a fog light that is running a 55w HID bulb. Hell, you might even burn your hand with one running 35w (depending on the construction of the light assembly). > > This is why 55w is not recommended in the fog lights. On many cars, specifically those with plastic lenses, it will crack the lens or burn the inside. > > Also…if you are experiencing flickering issues…you DO need a harness. Do you know what the harness does? It connects your power for the kit directly to the battery…thus giving it more ‘juice’ on startup. The reason why it flickers is because a lot of OEM wiring can’t handle the initial draw. I have this issue on my Infiniti. Got the harness, no more startup problems. > > A Resistor, when it comes to car lighting, is typically used on LED bulbs when applied to the side markers/turn signals. This prevents the ‘rapid blinking’ that happens when using such a bulb in such an application. Fixed Also, temperature is different than wattage… A 55W halogen draws the same power as a 55W HID… except when starting up! When the HID lamp initially lights it draws over 55W. I would recommend a relay and direct/fused battery connection. --- _[View the full topic](https://forums.speedlife.net/t/hid-install/262014)._
