 +=== The lights in my bathroom or room are blinking, switching off, or not turning on. Why? ===
 +One or both of the lightbulbs probably need to be replaced.  
 +Sometimes changing just one is enough – you can check by looking for **black stains** on the bulbs.  
 +To be safe, it’s best to replace **both bulbs** at the same time.
 +
 +----
 +
 +=== What kind of lightbulb do I need? ===
 +Use **Philips Master PL-C 18W 4P**.  
 +There are different color variants (e.g. **827** or **840**), but the important part is that it has **4 pins (4P)**.
 +
 +----
 +
 +=== Which color temperature should I use? ===
 +  * **Room/Kitchen:** 2700K – warm white (incandescent tone)
 +  * **Bathroom:** 4000K – cool white
 +
 +----
 +
 +=== Where can I buy them? ===
 +You can find them on **Amazon** or in hardware stores such as **OBI**.
 +
 +----
 +
 +=== How can I replace the lightbulbs? ===
 +You can ask **Lapic** to replace them (he usually charges around **50 €**),  
 +or you can do it yourself — it’s quite simple:
 +
 +  - **Switch off** the lights.
 +  - Make sure you’re standing **securely** and can reach the fixture safely.
 +  - **Remove the white cover** by pulling it down gently while twisting it a bit.  
 +    It may make some metal sounds – that’s normal.
 +  - Hold the **connector** with one hand and the **base of the bulb** with the other.  
 +    Pull the bulb **horizontally** out of the socket (it may require some force).
 +  - Find the **notch** on the connector and align it with the one on the new bulb.
 +  - **Push** the new bulb in until it clicks into place.
 +  - **Reattach the white cover.**  
 +    This part can be a bit tricky – push the metal clips gently until everything fits snugly.

 +**Tip:** If you replace both bulbs at once, you’ll have even light and won’t need to do it again soon.
