I’ve had my 2013 TSX for about 10 years and was looking to make some upgrades to the interior lighting, specifically the map dome lights and courtesy lights/door lights. While the stock bulbs in the car work, they are dull, yellow, & do not offer that much light output.  I was really just looking for something that was brighter and more modern. My thought was LED's could offer the best of both.

First Impressions of Lasfit LED Bulbs

After specifying the bulb types I needed,  Lasfit customer service(Hank)  helped provide the Lasfit equivalents for the map dome lights (Bulb type: DE3175, SKU: L-31MM) & courtesy lights (Bulb type: T10/194/168, SKU: v white color) and i was able to place an order. I received the bulbs within 2 days, which was pretty fast.

Pictures below show how the bulbs arrived inside the packaging. The overall packaging was good and the bulbs were secure inside their packaging.

My initial impressions of the bulbs were that they were of good quality & well constructed. 

Installation instructionsof the courtesy/door & map dome lights

Courtesy Door lights

For the Acura TSX,  there are a total of 4 courtesy/door lights and the installation process was the same for all 4 doors. No tooling was required for this installation.

1. To remove, push the lens cover up and then pull towards you and the cover will come off.

2. Use gloves, if needed,  to pull the stock bulb from the assembly as it may be hot

3. Insert the LED bulb straight into the assembly, with the circular portion facing towards you.

4. Once confirmed the bulb lights up, install the lens cover back on starting with the top tabs(green arrow in image above), push it in, and then push the bottom tabs in(red arrow in image above).

 5. Repeat steps for all other doors.

Map Dome Lights

There are a total three(3) map dome lights, two in the front, one in the rear. A flat head screwdriver was used for the installation, specifically to remove the lens cover and aid in removing the bulb from the contact points(if you can’t remove the bulb by hand).

Front Map Dome Lights

1. Insert a flat head screwdriver on the inner side of the lens cover(shown by red arrow for both driver & passenger lens covers) and gently pull down towards you. Remove the lens cover.

2. Use gloves to remove the bulb as it may be hot. Alternatively, use a screwdriver to aid in removing the bulb off the contact points
3. Insert the LED bulb into the assembly with the LED light facing you until it is firmly in place. For this LED bulb, there is no polarity so it can be inserted in either direction.

The Lasfit L-31mm was slightly wider & the Lasfit T10 were slightly longer than the respective stock bulbs, however no issue with installation or fitment.

Review & Final Thoughts

The installation process was fast(took about 10-15 minutes to replace all the bulbs) & straightforward with minimal tooling required. After installing all the bulbs, my initial thoughts were positive & I was satisfied with the light output that the LED bulbs offered over the stock halogen counterparts. The improvement in brightness is night and day. This definitely met my expectations in terms of what I was looking for with the switch to LEDs.

The verdict is still out and only time will tell on the longevity of the product(s) and performance(over time), but the LasFit LED bulbs are a great option & I would recommend it for anyone looking to upgrade their factory stock halogen bulbs for a brighter alternative.

Also shoutout to Lasfit customer service, Hank. He was very helpful & responsive throughout the whole process addressing questions, providing support & providing speedy delivery of the product.
