Looking for replacement light bulbs for a Monte Carlo fan? The important thing to look for and understand is, what wattage do you need for a replacement bulb. Try replacing the bulbs with the same bulb type you have now. Not all bulbs will fit in every socket - you need to match up the size, style and wattage.
Light Neck Fitter
If you are trying to install a new bulb and the neck appears to be broken, you can replace the neck. The neck fitter is where the bulb connects to the fan. Sometimes, the neck or sockets can become damaged through pulling too hard, years of age, installation & re-installation, etc. Obviously, it's never the intent to damage the neck - but it certainly does happen, or the replacement parts would not be available on the market.
A common neck replacement is a 4 light neck, or a 2 light neck to replace a broken neck for a Monte Carlo light kit. Sometimes it may also be cheaper, or more cost-effective to simply buy a new light kit as well. The cost of a new light kit could be under $50 at times, depending upon which one you originally purchased. If you are not sure of the part number you need to replace a light kit, try looking in the manual that came with the fan. If you don't have the manual, you can find it online as long as you know the model number of the fan. If you're really stuck and don't even know the model number, there is a way to figure that out by taking a look at the base of the ceiling fan. You may need to look on the canopy or even inside of the canopy to find the model number.
