Why Lorry Side Marker Lights Are Necessary
From my experience driving large lorries, I’ve come to realize just how important side marker lights really are. These lights make my vehicle much more visible to other drivers, especially in low-light conditions or bad weather. When I’m navigating narrow roads or busy highways at night, those small lights outline the length of my lorry, helping others judge my size and position better.
I’ve also noticed that side marker lights significantly reduce the chances of accidents during lane changes or turns. Since lorries are longer and have bigger blind spots than regular cars, these lights act as a crucial warning to other road users. They give everyone a clearer idea of where my vehicle ends, which is vital for safety.
Overall, my side marker lights are not just a legal requirement—they’re a key part of keeping me, my cargo, and other drivers safe. Without them, driving a large vehicle would feel much riskier, and I wouldn’t have the same confidence on the road.
My Buying Guides on Lorry Side Marker Lights
When I first looked into upgrading the side marker lights on my lorry, I realized there’s more to consider than just picking something that looks good. Over time, I’ve learned a lot about what really matters when choosing the right side marker lights. Here’s what I focus on to make sure I get the best fit for my vehicle and needs.
Understanding the Purpose of Side Marker Lights
For me, side marker lights are essential safety features. They help other drivers see the length and presence of my lorry, especially at night or in poor weather. Knowing their role made me appreciate why I needed reliable, bright, and durable lights.
Types of Side Marker Lights
There are a few types I came across:
- LED vs. Incandescent: I prefer LED lights because they’re brighter, last longer, and consume less power. Although incandescent bulbs are cheaper initially, their lifespan and brightness didn’t satisfy me.
- Flush Mount vs. Surface Mount: Flush mount lights look sleek and are less prone to damage, but surface mount lights are easier to install and replace. I chose based on my lorry’s design and how often I want to handle maintenance.
Brightness and Visibility
I always check the brightness level, usually measured in lumens. For my safety, I want lights that are bright enough to be seen from a distance but not so glaring that they blind other drivers. The color is also important — amber for the front and red for the rear side markers, which I stick to for compliance and visibility.
Durability and Weather Resistance
Since my lorry is exposed to all kinds of weather, I look for lights with a high IP rating (Ingress Protection). An IP67 or higher means they are dust-tight and waterproof, which is crucial to avoid failures during heavy rain or muddy conditions.
Size and Fitment
I always measure the mounting area on my lorry before buying. Lights come in various sizes, so ensuring the new markers fit perfectly without modifications saves a lot of hassle. Also, I check if the mounting holes align or if the kit includes adapters.
Power Compatibility
My lorry runs on a 12V electrical system, so I make sure the side marker lights are compatible with this voltage. Using incompatible voltage can cause dim lights or even damage the wiring.
Ease of Installation
Sometimes, I like to do the installation myself. I look for lights that come with clear instructions and all necessary mounting hardware. Plug-and-play models are a bonus because they reduce installation time and mistakes.
Legal Compliance
I always verify that the side marker lights meet local regulations and standards. This usually means they need to be DOT or ECE approved. Compliance ensures I won’t run into legal trouble during inspections or on the road.
Price vs. Quality
While it’s tempting to go for the cheapest option, I’ve learned that investing a bit more upfront on quality lights saves me money and trouble in the long run. Cheaper lights often fail sooner, so I balance cost with durability and performance.
Additional Features
Some lights come with extras like reflective surfaces, different lens colors, or multi-functionality (e.g., side marker plus turn signal). I consider these based on what I want for my lorry’s lighting setup.
—
In summary, when I shop for lorry side marker lights, I focus on safety, durability, proper fitment, and legal compliance. Taking the time to evaluate these factors ensures I get reliable lights that keep my vehicle visible and road-legal. Hopefully, my experience helps you make a confident choice too!
