Some months ago , a customer want to find A4L door sill in white or red color , I looked through the market but only Blue one available . At last , I really hope to help him , so try to revise the light color by myself .
Firstly , I have to buy the blue one .
I tear off the back sticker then I see three items behind.
see these things in front .
I had thought it should be good if by EL light , I bought the red one as sample .
But when I try to replace the blue one , I found that it is wrong , the film has color itself . The red EL light seems dim .
Besides the blue film , I believe it is perfect .
I also prepare a 3W White SMD light , if put behind the film , it is very bright , looks light blue because of the blue film .
I take another picture to prove that .
This is the white SMD light , it is not enough long , but I can purchase longer one .
What a surprised for this blue film , why they don’t use transparent one in black shadow ?
EL light use 3V , has to install a small relay to emulate the light , so although the light is beautiful , it is not the best choice .
I waited some days for my booked LED Plate light , they are various in voltage , here is 1.9V , 3.7V , 12V , but lighting output is same . It is the same light as A4L sample now .
(Red one )
(Yellow one back)
(Yellow one front)
(Blue one , which is 100% same as my A4L sample )
(white one )
( in fact , the white one has 9 led beads , it is quite bright )
At last I install the white one back to the A4L door sill , it is simple too , I have glue , 3M sticker , just waste some time on it .
However , revise the Audi A4 door sill light is an interesting work but waste time and money . I have to buy welding tool , LED sample ( the led factory request big money if just buy sample ) , stickers , glue , power bank before start to work . It seems that in fact I pay the value is more than the products itself . Anyway , at last , my customer is happy to see his white color door sill .
Customer happiness is my happiness , when I get good remark , I think it is worth . Enjoy !
