Story

I am using a two-hopper redstone clock to make a redstone lamp blink on and off as an indicator. The hopper clock looks like this:

The lamp is supposed to blink on and off at a constant rate to indicate to the user that the item that the lamp represents requires important attention.

Problem

The redstone lamp is expected to have a 50% duty cycle, that is it is on for the same amount of time as it is off. Instead, it stays on for a little longer, like so:

This is not ideal. The redstone lamp should stay on for the exact same amount of time that it spends turned off.

According to the Minecraft Wiki:

A redstone lamp activates instantly, but takes 2 redstone ticks to turn off (4 game ticks, or 0.2 seconds barring lag).

This means that in my case, the redstone lamp has a 75% duty cycle. This makes the indicator look very sloppy and floppy to the end user. A 50% duty cycle will make the lamp indicator more clean and make the user interface seem more professional.

Core question

What is the most compact way to compensate for the redstone lamp deactivation delay in a fast redstone clock?

There is already a very good answer below, however this question is not closed. If you have a better method, feel free to pitch in!

Answers that will be accepted include:

• Different clock circuits that have built-in functions to mitigate the redstone lamp.
• Modular devices that connect to an existing redstone clock to compensate the delay.

Please note that I cannot accept answers that are:

• Suggestions to use a different clock circuit, but using a compensation method that has already been shown here.
• Answers that are just images without justification.
