Step-by-Step Drawing Guide
Step 1: Draw the Outer Bulb Shape
Start with a large rounded outline, like a slightly stretched balloon. Leave a short flat area at the bottom with small curved sides for the bulb base. Keep the line light so it is easy to adjust later.
Pro Tip: Keep the top smooth and rounded, while making the bottom slightly narrower for a natural bulb shape.

Step 2: Add the Bottom Base
Draw a short rounded rectangle under the bulb to begin the metal base. Place it against the bottom of the glass shape, making it narrower than the bulb body. Keep the lower edge steady and soften the corners.
Pro Tip: Keep the base centered under the bulb so the whole light bulb looks balanced.

Step 3: Draw the Lower Screw Base
Add a short cylinder-like section under the base for the bulb’s screw part. Curve the sides slightly inward, then connect them with a rounded bottom line. This makes the bottom structure of the light bulb feel more complete.
Pro Tip: Keep the screw base close to the width of the upper base, but make the bottom slightly narrower.

Step 4: Add the Screw Lines
Draw two horizontal lines across the lower screw base to show the metal ridges. Add a small rounded bump at the very bottom for the contact point. Let the lines follow the width of the base and keep both sides mostly even.
Pro Tip: Do not place the horizontal lines too close to the edges, so the screw base stays clear.

Step 5: Add the Glass Highlight
Draw a short curved line near the upper left side of the bulb to show a reflection on the glass. Let the line follow the curve of the outer bulb shape. Keep it inside the bulb, without touching the edge, so it looks like a highlight.
Pro Tip: Keep the highlight short and light, and place it high to make the bulb feel more glassy.

Step 6: Draw the Filament
Inside the bulb, draw two upward support lines leading to a curly filament. Shape the filament with two small loops so it looks like a glowing metal wire. Start these lines above the base and keep them inside the glass outline.
Pro Tip: Place the filament slightly below the center of the bulb to keep the drawing balanced and natural.

Fun Facts
- A light bulb works by using electricity to create light.
- The glass part protects the delicate parts inside the bulb.
- The curly filament shape helps make the bulb look bright and recognizable in drawings.
Pin it now, Draw later!
Now your light bulb drawing has a rounded glass body, a metal screw base, a shiny highlight, and a detailed filament inside. You can trace the final lines with a marker, erase extra pencil marks, and add soft yellow color to show glowing light. Try drawing another light bulb with a slightly different shape to practice this step by step drawing method.
