What You'll Learn
Using spray paint
Painting plastic can be tricky as it is a non-porous surface, so the paint has little to stick to. However, with the right preparation, it is possible to successfully paint plastic.
Firstly, you need to prepare your workspace. Choose an area with good lighting and cover your work surface with newspaper or a plastic tablecloth. It is important to ensure that your plastic dome light cover is clean so that the paint can adhere properly. Use soap and water, or something stronger like mineral spirits, TSP substitute, or denatured alcohol to clean the surface. You can also use a product like Krud Kutter to ensure the surface is grease-free.
Next, you will need to sand the surface of the plastic dome light cover to create some 'tooth' for the paint to adhere to. This can be done by hand using sandpaper, or by spinning the globe and sanding off the gloss surface while it spins. If you are sanding by hand, you can use a finer-grit sandpaper to gently roughen the surface. Wipe the surface with denatured alcohol after sanding to remove any dust or residue.
Once the surface is prepared, it is time to apply the paint. Choose a spray paint that is specifically designed for use on plastic, such as Krylon or Rustoleum. Shake the spray paint can for a few minutes to mix the paint and ensure a smoother application. Hold the can 12 to 18 inches (30 to 46 centimeters) away from the surface and apply light, even coats of paint in a sweeping motion. It is important to apply several thin coats of paint rather than one thick coat to achieve a smooth finish.
Finally, you can apply a light coat of polyurethane sealer to the painted surface for extra durability. Choose a finish that appeals to you: matte, satin, or glossy. Again, it is important to apply several light coats of sealer rather than one thick coat to avoid a tacky finish. Allow the paint and sealer to dry completely before handling or reinstalling the dome light cover.

Adding colour filter sheets
To tint a plastic dome light cover, you can add colour filter sheets. These sheets are available in a variety of colours, such as red, green, orange, purple, and blue, and can be cut to size to fit your light cover.
One option is to purchase a pack of coloured overlays, which typically come in a variety of colours and can be cut to the desired size. For example, Amazon offers a 16-pack of 20 by 20 cm coloured gel light filter sheets in eight different colours. These sheets can be cut to size and placed over your light fixtures to create the desired lighting effect.
When selecting a colour filter sheet, consider the thickness and heat resistance of the material. Some customers have reported that certain sheets are not thick enough and warp when exposed to heat. It is also important to note that colour accuracy can vary, so be sure to read reviews before purchasing.
In terms of installation, you will need to remove the existing dome light cover. This can typically be done by twisting the cover or applying upward pressure and wiggling it back and forth to unscrew it. Once removed, you can cut the colour filter sheet to size and place it over the light fixture.
Keep in mind that colour filters work by allowing only certain wavelengths of light to pass through, so the resulting light colour may not be exactly as expected. Additionally, LED light sources are not broad-spectrum, so the light level through the filter may be reduced.

Installing an RGB LED light strip
To tint a plastic dome light cover, one option is to install an RGB LED light strip. Here is a step-by-step guide on how to do this:
Plan the Installation
Before you begin, decide where you want to install the LED strips and measure the length of the area to ensure you have enough strip lights. Consider the power source location, as you will need to plug in the lights. Longer strips will need more power, so ensure your power supply can handle the total wattage.
Prepare the LED Strips
Most LED strips can be cut at specific points to adjust their length. Look for cut lines on the strip and use scissors to trim them as needed. Check the voltage requirements of the LED strips (they are typically 12V or 24V) and ensure your power supply matches to avoid damaging the circuitry.
Clean the Surface
Dust and grease can prevent the adhesive from sticking properly, so clean the surface where you will be installing the LED strips.
Install the Strips
Peel off the backing from the adhesive tape on the LED strip and carefully press it onto the surface. Go slowly to avoid any wrinkles or bubbles. If you need to connect multiple strips, use electrical connectors. Strip the wire ends, insert them into the connector, and secure them tightly.
Power and Control
Plug the end of the LED strip into the power supply, ensuring the voltage matches the strip's requirements. Once all connections are double-checked, turn on the power and use the remote control to operate the LED strip lights. Some controllers may also have Wi-Fi capabilities, allowing control from a smartphone.
With these steps, you can install RGB LED light strips to tint your plastic dome light cover and create a unique lighting experience.

Using cardboard circles
To begin, measure the size of the plastic dome light cover and cut the cardboard accordingly. You will need a piece of cardboard that is large enough to fit snugly inside the cover, blocking the light. Once you have cut the cardboard to the correct size, carefully place it inside the plastic cover, ensuring that it is secure and will not fall out.
It is important to note that while this method can effectively dim the light, it may cause the light fixture to become warm to the touch. As such, it is essential to exercise caution and ensure that the light is not left unattended for extended periods. Additionally, consider using flame-retardant cardboard or coating the cardboard with a fire-resistant spray to mitigate the risk of fire hazards.
When cutting the cardboard, precision is key. Ensure that the circles are cut as evenly as possible, as any uneven edges or rough surfaces may show through the light cover, affecting the overall aesthetic. Taking the time to cut the cardboard neatly will ensure a more uniform and pleasing final result.

Installing a dimmer LED
To install a dimmer LED, you will first need to determine the type of dimmer and power supply you require. Dimmers come in two basic wiring configurations: standard single-pole dimmers and three-way dimmers. If only one switch controls the light, a single-pole dimmer is required. If two switches control a single light or a group of lights, a three-way dimmer is necessary.
After determining the number of switches, consider the number of bulbs and their total wattage. Check the rating on the dimmer switch to ensure it can handle the wattage of the bulbs.
Once you have selected a suitable dimmer and power supply, turn off the power at the circuit breaker box. Confirm that the power is off by flipping the current switch on and off or by testing the circuit with a voltage tester.
Next, remove the existing wall plate and mounting screws holding the switch to the wall box. Gently pull the switch away from the wall. If replacing a three-way switch, one wire will be connected to a differently coloured or labelled "COMMON" screw. Tag this wire with electrical tape for identification when wiring the new dimmer.
Now, you can install the new dimmer switch. Tighten the screws holding the dimmer to the electrical box. If your dimmer has a removable knob, gently pull it outward before attaching the wall plate. If the dimmer has a separate wall plate, tighten the mounting screws. If your dimmer has a screwless design, screw the wall plate adapter to the dimmer, and snap the wall plate onto the adapter.
After installing the wall plate, return to your circuit breaker and turn the power back on. Test the dimmer to ensure it is functioning correctly.
Additionally, if you are installing a dimmer for LED strip lights, you will need a PWM (Pulse Width Modulation) dimmer. The PWM dimmer will be connected after the power supply, with a DC input for power and a DC output for power and dimming signals to the LED lights.
For a more elegant solution, consider installing a dimmable driver, which offers superior dimming control compared to inexpensive PWM dimmers. A dimmable driver installation is similar to a non-dimmable power supply. On the DC (output) side, connect the positive and negative wires to the LED light strip or other low-voltage lighting products.
To tint a plastic dome light cover, you can try using a colour gel sheet or a colour filter sheet over the light fixture. These sheets will alter the light by allowing only certain wavelengths to pass through. However, the results may not be optimal, especially with LED light sources. Alternatively, you can install an RGB LED light strip, which can be controlled to emit a wide range of colours.
